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 and side rails to accommodate a wide variety of Rhino-Rack accessories, including rail systems, awnings, light brackets, and more. The platform mounts directly to your vehicle's naked roof using RTS tracks and RC-style 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 and side rails 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

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.

side railsfront and side railsfull rails

Additionally, a rail system can be installed to enhance your application. The rails bolster the safety of your load and create additional tie-down points for your gear. They are easy to install and simply bolt into the channels on the platform's side rails. This platform is compatible with side rails (RR43144B - sold separately), front and side rails (RR43164B - sold separately), and full rails (RR43183B - sold separately).

Utilitarian Design with Rugged, Off-Road Look

pioneer aerodynamic design

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.

wind fairing

An optional wind fairing (RR43250 - sold separately) is available to cut down on wind noise even further.

Strong, Durable Construction

pioneer close up

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 a custom track system on your vehicle's naked roof. The platform comes unassembled, so you will have to put it together before proceeding to the installation. After this is complete, use a rivet gun to install the RTS tracks to your vehicle's roof. These tracks provide adjustable mounting points. Then, simply bolt the RC legs into the tracks' top channels and attach the spacer blocks to establish a level surface for the platform. The bars attached to the bottom of the platform connect to the legs and secure the Pioneer in place.

Review from a similar Pioneer in Roof Rack

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. 719282

Review from a similar Pioneer in Roof Rack

This rack is super solid. Took about an hour to put it together and another hour to mount it on my truck. Clear instructions and very easy to install yourself with even a basic skill set. Etrailer got it to me in 3 days for free! Can’t say enough about the service and the prices from etrailer. 599244

Review from a similar Pioneer in Roof Rack

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!! 614433

Iwe continue to enjoy and appreciate the platform- AND i have addedthe rails, which have really helped with securing a load!!

Review from a similar Pioneer in Roof Rack

Awesome rack! Solid functionality and sharp looking on my 4Runner. Only downside is lots of parts and pieces/screws/bolts/washers to manage to put together...worth it in the end, however. Price and service from etrailer also could not be beat, and I did my research! Thank you all around. 593032

Review from a similar Pioneer in Roof Rack

First of all congratulations to E-Trailer on the shipping. I ordered my pioneer platform and the full rail kit at the same time. The rail kit was not in stock and had to be shipped from the manufacturer. Worried that the shipment might not make it time for my upcoming desert trip, I called etrailer and voiced my concerns. Long story short, I was given a ship date that wouldn’t have given me much time for the install and I ended up getting it four days earlier. Super easy to install and very strong. I’ll have to give a follow up review after I put it work in the coming weeks. 616480

Review from a similar Pioneer in Roof Rack

Fantastic experience! I spent weeks researching rack options for my GX460. At the end of my rope with literally NO good options, the good folks at etrailer talked me thru some great ideas and I went with the RhinoRack Universal Platform, attached to Yakima RailGrab Towers. My etrailer order was delivered within 48hrs and installed within another 12hrs. Great fit, great look. No rattles and surprisingly, no wind noise. I’ll be back for accessories! GREAT experience. 706244

Review from a similar Pioneer in Roof Rack

Bought the Rhino Rack 60 x 54 platform to mount over the bed of my '20 Jeep Gladiator. Then I will mount a Thule Cargo Box onto platform for additional storage of camping gear. I decided to go Rhino Rack because it really gives you options. I like the antenna mount options for my CB and Ham radio. Top quality materials and finish. Much nicer than I had anticipated. Package came well packed and in good order. But be advised it's pretty heavy. Assembly will look quite daunting at first. I would advise finding an elevated surface that is larger than the platform you purchase. One easy way is to empty your garage and get two 3 x 6 folding tables or 2 sawhorses and a piece of plywood. Put down a light colored cloth or blanket on work surface as not to scratch your platform. Make sure you received the size you ordered prior to opening box. Unpack box and find hardware box. I had a small clear plastic fishing lure organizer in which I put all hardware in. Trust me, there's a lot of hardware. You may then count all hardware against packing list if you wish. Set that hardware aside. Preview instructions as they are fairly clear. Then just lay out all the pieces upside down in the order they go together making sure all parts are accounted for. Then follow the instructions and you should be good to go. Have no hesitations in buying from etrailer. There customer service is fantastic and returns are super easy. 732386

Review from a similar Pioneer in Roof Rack

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. 519915

Review from a similar Pioneer in Roof Rack

Rhino rack pioneer platform JA8200 for Land Cruiser 80 Series. Awesome product, aluminum high build quality, low profile and round edge design that matches well with 80 Series's curvy line. I decided on this rack for #1 functional reason, "fitting into my garage" after my rig's been lift and upsized tires. #2 reason is aesthetics fitting the LC80. ARB was too high on profile, other one piece design was too bulky for shipping. Great product. The only minor issue I had was the 80 Series has a bit curvature (~1/4") on rain gutter, with highest point at the middle area. This requires a bit adjusting/playing with foot positioning and use of shimming. eTrailer customer service was great, with Bryan sent me the missing part once notified. Great place to buy with free shipping. 555298

Review from a similar Pioneer in Roof Rack

I have been looking a long time for a good roof rack for my 2018 Toyota 4Runner and decided on the Rhino Pioneer Platform with the Backbone mounting system. Removal of the factory side rails was very easy. Putting the platform together was relatively easy and installing the Backbone mounting system in the existing factory holes was also quiet easy. Attaching the platform to the Backbone mounting system was a bit more challenging for me. I tend to take my time and double check everything as I go. Total build and installation time was approximately 6 hours. The end result is fantastic, it looks great, is very solid, will easily accommodate my needs (Rooftop Tent, lumber trips to Home Depot, Kayak, Mountain Bike, etc.). I have taken a couple of trips on the highway 80MPH and the wind noise is noticeable but acceptable. I will probably purchase the wind deflector and hope this will also positively impact the gas mileage. The people at etrailer are exceptional to deal with! Their pricing is good, their communication is excellent, shipping was fast, the packaging was perfect with all parts well protected and nothing missing. If you have any questions about the product or installation, they are knowledgeable and happy to help. The rack is solid, good looking, and well made. At this point my only concern is the high price for various accessories. I highly recommend this roof rack system and dealing with etrailer is a pleasure. 853981

Review from a similar Pioneer in Roof Rack

Product arrived in a timely manner. Shipper banged up the outer package pretty bad but all products inside were wrapped all snug and secure. Only complaint is the plank came with the plank inserts already set. During shipping, one of these inserts shifted down well inside the plank. It took a very long time to retrieve it. Also, having those inserts already in place, one had the nut reversed and had to be removed, that as well took a long time to pry out of the plank. It's a great platform, I now own three. I would definatelt purchase again from etrailer. 851858

Review from a similar Pioneer in Roof Rack

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. 837900

Thank you for the order. First time buyer at etrailer. Process was quick, customer support messaging was very informative along the way. Product Itself 1. Definitely need to read the manual which was included in the packages and provided electronically by etrailer. 2. If you follow the manual, should be no problems, but pay attention to detail. 3.
