pioneer in use on trail

Built for off-road use and tested in harsh Australian conditions, the Rhino-Rack Pioneer platform is a comprehensive solution for your cargo carrying needs. This platform's large, flat surface lets you carry more gear than a typical roof rack, freeing up space inside your vehicle. The Pioneer uses integrated channels in the planks, side rails, and frame to accommodate a wide variety of Rhino-Rack accessories, including awnings, light brackets, and more. The platform mounts directly to your vehicle's factory tracks using RLT600 roof rack legs.

The Perfect Roof Rack for Any Outdoor Lifestyle

pioneer with accessories

Whether you are overlanding, camping, or tailgating, the Pioneer platform's ample surface space lets you carry a large amount of cargo and gear. This helps free up space inside of your vehicle so you and your passengers can travel comfortably. The integrated channels located in the planks, side rails, and frame let you install channel-mount accessories, like an awning or kayak carrier, similar to a traditional roof rack. But, there are also several accessories that install exclusively to the Pioneer platform, such as the aluminum folding ladder and gas can holders. And because of the platform's design you can utilize many of these accessories at the same time.

Accessory bars (RR43138B - sold separately) can be added to accommodate clamp-mounted accessories that fit in the space between the platform's planks, such as bike carriers and cargo boxes. And because the bars have C-channels, you can use them to mount additional channel-mounted gear in the open space between the planks. By installing the accessory bars in the platform's integrated channels, you gain all the advantages of a traditional crossbar system, while maintaining the generous surface space of the platform.

Utilitarian Design with Rugged, Off-Road Look

The Pioneer platform was designed with utility in mind and features a rugged, off-road look. The low-profile tray was also designed to be aerodynamic to help reduce wind noise and drag.

Strong, Durable Construction

Strong, yet lightweight, the platform's frame is constructed of aluminum and includes reinforced nylon connectors. Since these materials are powder coated and non-corrosive, the platform won't rust or fade when exposed to the weather. Rhino-Rack has rigorously tested the Pioneer in the harsh Australian outback, ensuring it's built to withstand anything your adventures throw at it.

Custom Fit Installation

This Pioneer platform rack is custom fit for your vehicle and includes all the parts necessary to install it in the factory track system on your vehicle's roof. The platform comes unassembled, so you will have to put it together before proceeding to the installation. After this is complete, simply bolt the RLT600 legs into the tracks' top channels. The bars attached to the bottom of the platform connect to the legs and secure the Pioneer in place.

I did a lot of research before settling on this roof platform. I’m really happy with the build quality and once it’s all together it has a lot of strength and versatility. My ONLY complaint is that the “Quick Foot” mounting feet for the factory rail that was sent to me did not have matching key codes. The codes are clearly listed on the boxes and someone at didn’t bother to grab a matching set. Bummer.
After waiting for shipping and finally pulling it all out for the install I was too far into the project to ask for replacement feet. I just installed what was sent.


We bought the Pioneer Platform to go ontop of our Ford Excursion. I called to make sure that this was the model that came with the mounts that fit in the factory luggage rack rails. etrailer was super helpful over the phone. They had really good customer service. We put the Smittybilt Overlander XL rooftop tent on the platform. It all works great. I'd highly recommend etrailer to anyone everyone.

2000 Dodge Journey

The rack is outstanding! It's extremely well built and sturdy, and fit my Excursion perfectly. I highly recommend it. shipped it quickly and showed me where it was every step of the journey, and I was able to be at my house when it arrived (in two large boxes). 100% satisfied with both etrailer and the roof rack.


Great product, excellent quality, great finish very sturdy and mounted to my Vortex bars perfectly.

Couple of cons but I'm not going to knock down the review because of it. Product came with instructions that are out of date for the new racks they are shipping. Platform also came with some missing hardware. Two missing nut retainers,two nuts,two screws and two washers. Was able to put it together with Hardware I had on hand..


I called etrailer to verify fitment on my 2013 Ford E-350 XL. Everything arrived sooner than quoted, and instructions were clear. It took me approximately 6 hours to assemble by myself. I had 3 buddies over to put it on the van because it is ~100lbs and 100”x62”. We put towels on top of the van and slowly slid the fully assembled rack on top of the van. It took a while to level everything (30 mins?), but overall went on well and looks great.

The instructions didn’t clarify where the C-channel bars are supposed to be spaced to, but I used basic math skills and spaced each C-channel evenly spaced. It feels very strong. I believe it was 33mm on center for each C-Channel.

Looking forward to camping in a few weeks!


Fantastic rack, easily modified to accommodate tents/cargo/whatever. It's not quiet though, so do yourself a favor and get the faring.


Exactly as advertised! I love this rack. I have it on the top of my 2014 E350. No


This is a solid and versatile rack. Really well constructed. I bought mine wider than the vehicle for extra space. I found many generic options for attachment accessories. It's flat when I need it to be for airport parking garages. One year later, it's still awesome!


I bought this roof rack to mount on my 2018 Toyota TRD Off Road 4Runner. The reason I purchased it was because of the versatility that this product offers. There are many roof racks out there for my vehicle. Some are cheap and some are expensive. Some racks are smaller and some are full size. I was looking for a rack that wouldn't break the bank as well as cover a majority of the roof (without drilling). I have two young kids and I'd like to get them out more. Hence, buying the 4Runner as well as the rack. This rack will enable me to load a ton of stuff on it in the future such a roof top tent, awning, etc. Even though I'm somewhat handy, the installation did take around 3-4 hours. I did have one other person helping me. I highly recommend having an additional set of hands helping during the installation. The sides rail installation was easier than I thought it would be. The platform itself took longer to install. Overall: very happy with this product. I highly recommend it.


The instructions on etrailer were way better than the ones that came from rhino. The rack is awesome seems to be well built I would highly recommend it to anybody looking at doing any over-landing or tent roof camping


Overall, I like the rack. I use it for a hard shell RTT and it has held up well through several camping and off-roading trips. I chose this rack for the low profile look, weight and mounting system.


Just perfect, my shipment arrived in a couple of days. There was a hole in the box that may have occured during shipment that resulted in one of the slat being scratched, luckily I had black satin paint so I just soared over it so problem solved. Took me a while to assemble the platform as fherr were a lot of bolts and nuts to turn. But the end result is a nice sturdy platform rack that I will be putting to good use for my family’s upcoming adentures.


Assembly was fairly easy and overall seems like a good product. I did have a couple of screws (2 of the Alloy Locking Tabs did not have the M6x20mm Security Head Screw (black) or associated washers) missing from the package but was still able to use as is. Hopefully I can have the screws and washers mailed to me.


Slik in design, tough in outlook, easy to assemble this is rhino roof rack awesome ready for today and future adventure.


This fits my 2024 Toyota Sienna that came with the factory roof rack + Cross bars. The material of construction look and feel high quality. The assembly took quite a bit of time because the bolts and nuts were labeled to match the instruction. The instruction could use a little update.


I will update this accordingly once issues are corrected. Received my Pioneer Platform Rack for my e350 Quigley Van. The box was highly damaged and taped prior to delivery. I unboxed and layed out everything. Missing the entire hardware box- no bolts, nuts, tool, corner pieces, nothing. Contacted E Trailer immediately and was told they would be sending out a complete set of hardware. Shipping on my rack was extremely fast, which is always appreciated. I am hoping that the parts box arrives as quickly so I can get this assembled and update my rating.


Well I must say I am impressed--with the Rhino Rack and etrailer! This big ole Pioneer platform package arrived really quickly and was in perfect shape in and out--none of this already opened noise you hear about from sketchy vendors. The platform quality is also really good; I didn't expect it to be so good. I also really like how low it sits; they were obviously designing this to fit the Outback just right. I am a happy camper! Thanks etrailer for making this process worry/pain-free.


Sturdy and very strong. Just what i needed for my Rooftop tent.


This platform rack perfect fit to my 2020 DURANGO GT. Easy assembly, easy installation and removal. I bought 2 years ago a trailer hitch receiver (code C13182) from your company and also satisfied with its use. I recommend ETRAILER.COM to all my friends. Thank you.


The RINO RACK AND PIONEER PLATFORM are a great addition to my little Wrangler.
etrailer folks were very helpful in determining exactly what I wanted and needed. The assembly instructions are very good - even though there are a lot of parts to assemble. I was able to complete the assembly by myself (with help getting the top off the jeep.) If I can offer a recommendation from my experience, I would pre-assemble the entire unit with the mounting brackets finger-tightened to the platform AND THEN set it on the roof - to insure that the holes needed to be drilled are in exactly the right spot. I had to re-drill two holes and maybe that was my own fault, but until I did, i could not get the platform to rest in the mounting brackets.
All that said, I am VERY PLEASED with the RINO RACK product. It is very secure, easily accessible, very low profile (3" from roof to top of rack), large platform that still allows removal of the Freedom Top on my rig. It will give me the extra carrying capacity as we tow the jeep behind the motor home from Arizona to Alaska and hit lots of back country for tent camping in the process!!


Great fit with the Rhino Rack backbone for Gladiator and the Bestop Sunrider.


This platform is awesome! Very sturdy and well made, and I love that the Rhino Rack branding is a metal plate. Not a sticker. Very easy to put together and put up on the roof rack! Very happy customer!


Purchased this about a month ago after having a mediocre cargo basket that started to rust after 2 weeks. This platform is not only more convenient and adaptable but it looks [really] great! Took some time to assemble but I made that every piece fit and lined up correctly. Nice finish and strongly constructed. I should have gotten this first! I also got the matching rail system to complete the set-up. Highly recommended. Shout out the the staff at etrailer for again for the great communication from start to finish!


Very helpful over the phone.
the item when it was promised.
Very good price.


I installed this on a '99 Lexus LX470 (Toyota Land Cruiser 100 series). I have had 0 issues with this rack and the options are seemingly endless.
Here is what I've had mounted to this rack:
1- Black Oak LED 40" light bar using Rhino Rack brackets
2- Max Trax recovery treads
3- Jerry Can
4- Mountain bike - had to spend 100 on correct rail/fork mount, but it works flawlessly
5- Oz Tent Foxwing awning - used Rhino Rack Foxwing brackets
6- Shovel / Hi-lift jack dual brackets - only had shovel mounted
7- Tepui Roof Top Tent - Kukenam Ruggedized - used Eezi Awn K9 brackets and made it super easy to mount.

My ONLY complaint is that for a rack this expensive (all racks are expensive) I wish they would rivet a metal "RHINO RACK" logo to the product. The decals start peeling after a short time and makes a really great quality rack look cheap.

I will also add this note: Add-ons and all the extras get really expensive. It's like stepping into vacuum for your money. Once you get over the initial investment, you've only just begun. Now, you've got to mount things to it and that's where you really have to PLAN IT OUT AHEAD OF TIME. You need to have a game plan of what you want to do with it, otherwise you will have a boat load of bolts/brackets/clamps etc. that you end up not using. There are usually more than one way of getting something attached. So, ask yourself if you really need that 100.00 bracket or if a ratchet strap will do the same thing. Also, don't get overcome by the "coolness" factor. Do you REALLY need that Hi-lift jack, or do you just want to keep up with all the Jeepsters out there. If you take that approach, you'll be ahead of the game.

I deducted one star for the decals and for all the accessories being so overly expensive....but they DO WORK REALLY WELL.

This is not a mark on Etrailer. Etrailer is AAA+ Their customer service is top notch and have always provided me with great communication and service.

  • What Platform Rack Do I Need For My Factory Roof Rack On My 2005 Ford Expedition?
    You can get a platform on your roof of your 2005 Ford Excursion but the one you're looking at # RR78AB is a track mount and factory crossbars do not have t-tracks on top. What you need is a kit that wraps around your crossbars like this one # RR42115BF. This is the heavest duty roof rack you can put on your car so it will be able to support the static weight of your Smittybilt GEN2 Overlander Tent XL.

  • Lower Profile Roof Platform Tray that Can Fit Roof Channels on Top of Camper Shell
    Since you want the lowest profile for the roof platform tray you'd actually want the Rhino-Rack Pioneer Platform Rack # RR78AB which is a similar size of 84 by 56 inch but can attach directly to the tracks you have on your topper. The Yakima setup would require a set of crossbars which would add height.

  • Do You Carry a Cargo Basket that Doesnt Use Towers/Crossbars?
    I have a solution for you. Unfortunately, we do not carry a cargo basket that installs directly into your tracks on your vehicle. However, If you wish to eliminate the Yakima crossbars and towers for a shorter rack on top of your 2012 Toyota Tacoma with a track system, one solution is to purchase a pioneer platform system like the Rhino-Rack Pioneer Platform Rack - Track Mount # RR78AB. The platform comes with dimensions of 84" long x 56" wide x 1-1/2" high and will install into your track...

  • 2005 Ford Excursion Flush Rail Roof Rack Recommendation for Luggage
    Since you're planning on hauling gun cases and luggage I highly recommend going with the Rhino-Rack Pioneer Platform Rack # RR78AB for your 2005 Ford Excursion. This measures 84" x 56" and connects directly to the flush rails on your roof, and the platform part will make loading and securing your cargo much easier on this than on just a standard 2-bar roof rack setup. The Pioneer has a wide variety of accessories that can be used with it as well, including; the Folding Ladder and Brackets...

  • Compatibility of Tie Down Points With Rhino-Rack Pioneer Platform Rack
    The Underside Tie Down Point # RRS606 will fit into the tracks on the underside of a Rhino-Rack Pioneer Platform Rack like the # RR78AB. Regular tie-downs # RR43VT and eye bolts # RR46XP are also available for the top channels on the rack.
