If you've read any of our earlier blog posts it's probably become quite clear that we at Nitro Gear and Axle are serious gearheads. To say we're obsessed with 4x4's, sports cars, and even RV's would not be an understatement. We simply love machines and we love modifying them even more. So no surprise when several years ago the idea of a go anywhere and tow whatever we want RV became a project here at Nitro.
These are the complete specs along with photos of the build and current state of the project. Please let us know if you have questions.

Buckstop 20x11" heavy duty single wheels with Goodyear G275 MSA 335/80r20 (41") Miltary Tires. The Goodyear tires are a recent change from smaller Continental's the rig ran for the past few years. So far the new tires have been a huge improvement in noise and road feel so we are very pleased with them.
Our plan is to start documenting the trips and places the RV takes us now that it's finally at a level where the bugs are worked out, performance is spectacular on the road and the onboard electrical systems are fully operation.
