Nice rack system, strong and durable. Used on a Ford e350 to mount solar panels. Only draw back, one of the L brackets that goes under the rain gutter was not bent square enough and this caused the bracket to slide off when tightened. I had to adjust this with a clamp and hammer, no issues since.

Thank you for the help putting together the perfect system for my truck. Exactly what I needed.

Added to my Ford Transit van to hold solar panels. Fit the factory holes well and we have had no problems. Exactally what we needed. I will be adding two more eventually but now we are having too much fun with the van.

When I bought this for my ram promaster not even the manufacturer could tell me how it rated. I was so new they had no comparisons. I’ve had it on my van for over a year. Traveling around the country through all kinds of weather. Rain, hail, snow, and sun in the desert.
This rack is awesome.!!

The heavy duty rhino-racks are very well built. There is wind noise. That can be muffled some by using uni-stut closure strips. Uni-strut fasteners fit on both the top and bottom of these bars making it nice for building your own custom tie down and attachment points

Order is lost. Only received half of it. Tape your boxes together like you did on previous orders.

Our bars did not arrive. It only takes three days to ship to Anchorage Alaska from anywhere CONUS.

Nissan Versa

This rack works perfectly on my Nissan Versa for carrying my two Perception Sound 9'6" kayaks. The Rhino-Racks look good to me. The kayaks can rest directly on the rubber pads on the rails, unlike the Yakama racks I had in the past that had bare pipe rails. Also, I expect I can buy parts to adapt this product to a different car without having to buy new towers. I am sorry there are not hooks or loops to attach bungees when carrying lumber. They are noisy in the wind, but less so when carrying the kayaks.

Hi Mike, I was researching roof racks for my 2013, 170 tall Sprinter Van ordered and I came across your post. I have a Yakima rack that I had on my old BMW that I was thinking of using until I saw your post. Did you install your own rack and solar panels? I was thinking of paying a local RV custom place, near here, to do all this work, but Im leaning to doing a lot of it myself. If you installed all the gear on top of your van, I have a bunch of questions:1 Ive order factory roof rails for my Sprinter, did you simply place the Rhino tracks inside the rail grooves and how did you bolt them down?2 What are the other accessories I see on top: Fan, Solar panels make$, A/C, Sat? Did you install all yourself, if so, was it difficult?3 Awning: What type and difficulty/cost of installation? 4 What are small devices on roof: white knob type device right lower on picOn left side of pic, front to back: white, flush 6disc, black protruding 6 knob, 6 flush, black, controller type box. Again, if you didnt install, who did and a what cost? Thxs for your patience!Joe

Amazing product. Fit, finish, quality is absolutely amazing!
Have hauled our bikes all over MI, through the UP, and back. They never moved. Rack is super simple to remove from the rails to grant full access to the PU bed.
I think this is one of the Best options out there for taking your bikes with you while still having your covered bed space. I also can install a Ski box for the winter. Ski's in the box while gear in the covered bed.

Kit was great, except my SnugTop cover required longer T-Bolts for mounting the tracks. The 1.5 inch ones provided were too short. It was a little tough sourcing T/Bolts that would work. It would have been nice if longer T-Bolts could have been an option from Rhino Rack.

I am normally a exclusive Amazon shopper, but etrailer gives equal or better service and has specialty items you just can't find anywhere else. The pricing is great also. This is my 4th order from them on this project and the response has been perfect and the shipping has been prompt. They even offered to take back an item that I did not need. I desperately wanted to mount my 19ft Kayak on my new RV and with some Rhino RT tracks, a Rhino Nautic kayak lifter, a few really heavy duty rivets, and some ingenuity, I was able to accomplish the task. I am replacing the current Nautic bars with the heavy duty bars. See the attached pictures.

Roof Rack for Winnebago Travato Class B Motorhome on 2017 Ram Promaster Chassis
The Thule TracRac TracVan # TH29613XT roof rack is designed to work with 2 pairs of the existing roof rack mounts on a Ram ProMaster. If your Winnebago Travato has those existing connection points on the roof, the TracVan ES roof rack would work perfectly for you. I've linked to a diagram showing what the mounts look like, and where they can be found on the roof. From the online photos I've seen, it appears the exterior of the ProMaster is unchanged from the cargo model, so it's very likely...

Do the Swagman Roamer LT Roof Rack for Pop-Up Campers and Camper Shells Have Load Stops?
Hey C.J.! I checked our website and Swagman's and did not see any options for load stops that work with the Swagman Roamer LT Roof Rack for Pop-Up Campers and Camper Shells item # S80510. That's a pretty old video you referenced, so I am guessing they're not available anymore. For a comparable set of crossbars that do have readily available load stops item # RRRLH, I recommend the Rhino-Rack Heavy Duty Roof Rack for Tracks item # RR38NP and item # RTC18. I think this is a far better system...

Will Roof Rails Work On a Teardrop Trailer T@B
I do have an option for you but roof rails won't work very well on a teardrop trailer, even if you were able to get the rails to conform, it's likely the accessories would bind due to the steep angles. Instead, you will need to use artificial rain gutter mounts which is what most other teardrop trailers use from what I found. I have attached some parts below.

Best Roof Rack System for 2001 Ford E350 Van
The gutter mounts we have are actually really sturdy if you get the right ones and install them right. Technically, you should have more weight capacity off the gutter mounts since the weight is distributed vertically through the gutters vs racks bolted onto your fiberglass roof. A good system for your 2001 Ford E350 Van is the Rhino Rack system with Square Crossbars # RB1800B-2 and Gutter Feet # RL150S10. You can switch the square crossbars for aero ones with 71" Vortex Aero Crossbars...

Roof Rack Recommendation for 2019 Ford Transit T250
The roof rack I recommend for your 2019 Ford Transit T250 is the Rhino Rack Heavy Duty rack part numbers # RB1800B-2 and # RRRLTPFC-2 because the crossbars of this rack are the best suited option for carrying ladders. The strip on the top channel has a no-slip rubber surface which helps keep them from moving and because the top channel has load stops made for it for this exact purpose. The bars are shaped more like a ladder rack than a roof rack and combined with a set of Rhino Rack Load...

What Roof Boxes Will Fit On The Rhino Rack HD Square Crossbars
You will have plenty of options for cargo boxes that will fit on the Rhino Rack HD bars # RB1800B-2. As a matter of fact you could fit virtually any roof box that we carry. Most cargo boxes are made with universally designed clamps, so they will fit any crossbar shape. The box does not have to be brand specific to the roof rack. So you could absolutely use a Thule or Yakima roof box. My favorite roof box is the Thule Force # TH6357B. This box (like most others) is compatible with virtually...

Recommended Rhino-Rack Crossbars That Works With A Retrax Pro Tonneau Cover
I did some research and unfortunately Rhino-Rack does not make the HD bars # RB1800B-2 compatible with your RetraxPro tonneau cover. The only kit they make that is desinged to be used with the Retrax Pro and Retrax XR tonneau covers is the Rhino-Rack Vortex Crossbars for Retrax XR and Mountain Top EVO-M Tonneau Covers # RRVA180B-RRRLT600. These crossbars have a maximum weight capacity of 220-lbs. measure 71" long x 3-1/8" wide x 1-3/16" tall, and will mount to the t-tracks on your Retrax...

Or if you are looking for a Pioneer platform the Rhino-Rack Pioneer Platform Rack # RR43QX is the one you need. Both systems attach to the gutter tracks along your 2010 Ford E-350 Van.

Rivet Holes on a Rhino-Rack RT-Style Roof Rack Tracks for a 2016 Mercedes-Benz Sprinter 2500

There is no need to remove your headliner or any of the lights/accessories on the interior.

The square load bars measure 65 inches long x 7/8 of an inch tall X 1-1/4 inches wide. The two crossbars have a weight capacity of 220 lbs. The Inno feet # INSD use the rain gutters of your vehicle to attach to the roof. The feet include a special wrench that will allow you to munt the feet to the van. The wrench makes installation quick and easy. For...

Can I Upgrade To 71" Rhino-Rack Heavy Duty Crossbars Instead Of 59" Crossbars On 2012 Jeep Wrangler?

While Rhino-Rack does not suggest using the 71" Heavy-Duty Crossbars # RB1800B-2 that you were looking at, you can certainly use them as long as they are not longer than the widest point of your vehicle which is usually the mirrors.

This rack can be used to mount the Rhino Rack Batwing Awning # RR33200 directly to the Vortex Aero crossbars # RB1800B-2 by using the top channels of the bars, so it's a great choice that gives you a high quality rack at a nice price point.

Long Track Roof Rack Solution for Sprinter Van with 170 inch Wheelbase
We have the 71 inch long Rhino Rack Roof Tracks part # RTC18 which would do best to run the length of your Sprinter 170 inch wheelbase model. This is our longest option and also the best choice. For feet then you'd want two sets of the # RLTF and then for bars you'd want the part # RB1500B-2 for a set of 59 inch long bars or # RB1800B-2 for 71 inch bars.
