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 crossbars.

The Perfect Roof Rack for Any Outdoor Lifestyle

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.

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.

Universal Fit on Most Crossbars

This Pioneer platform rack fits most crossbars and includes all the parts necessary to install it. However, it is not compatible with Rhino Rack Heavy Duty crossbars. The platform comes unassembled, so you will have to put it together before proceeding to the installation. After this is complete, simply use the clamps to connect the bars on the bottom of the platform and crossbars together. Alternatively, you can bolt the platform to the integrated channels on the crossbars using the upper clamp and included hardware.

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..

Its been a year since Ive installed the rack on my truck cover. So far it has been fantastic looks like new yet does everything I wanted to do and its the perfect size for the installation I have. I wouldnt hesitate buying another if needed, but if youre interested in some type of platform this is the one to get.

@DennisS Thanks for your kind words!


The Rhino pioneer roof rack and vortex crossbars are going to work great on my Ram Truck with Retrax tonneau cover to help me carry extra gear. I also have the Yakama HD overhaul rack for carrying my kayaks. Everthing fits perfectly!


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!

1 year review. I’m still loving this Rhino Rack Pioneer Platform Rack. I haven’t had any problems since I installed it. My biggest worry was it rusting here in Hawaii as I’m close to the beach and live in a area where I get a lot salt air that reeks havoc on anything metal. I still get a lot of compliments especially from other Rhino Rack owners. No regrets!


2011 Ford E350 Super Duty Van. Can’t beat the quality & all the options that can be used with Rhino Platforms! This will come in very handy! Thanks etrailer!!


Exactly as described. Bought this rack for my 37” spare tire. Still leaves room for me to add other items as needed on my bars.


Adds personality and efficiency with a lot of quality, this size (small)is perfect in my mini countryman. Thank you etrailer associates for your great service!.


Looks great very streamline


I like this platform easy to install. I just wished that there was a more knowledgeable place near me so I can get more accessories. Rhino rack has a lot of accessories and I’m not sure what fits my platform


Very happy with this purchase. I chose it for the size, light weight yet sturdy construction, and low profile. Initial assembly was straightforward and installing and removing it from my roof cross rails is pretty quick and easy. Have used it for a week-long family beach trip. There was a bit of wind noise on the highway, but nothing objectionable. The customer service was friendly and responsive in answering pre-purchase questions and processing my order.


works as designed



works very well to get cargo out of the back of the jeep. Even better, getting gas containers out of the jeep to the delight of my wife.



Nice qnd sturdy


Looks good will see you at last


Great product and service!








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!


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
