Custom GMC Motorhome Attempts Land Speed Record

We have shown off dozens of custom RV remodels, but it is safe to say none quite like this. How about a total ground up remodel of a 1970’s GMC Motorhome not for camping, but for breaking the land speed record? Clearly this motorhome is in a league of its own with its 600hp 502 cubic inch Chevy V8 with front wheel drive.

This custom GMC motorhome was custom designed to dethrone the “World’s Fastest Motorhome” holder in the Guinness Book of World Records, which currently is held by a Hymer AG Motorhome with a respectable 128.6 mph.

The story of this extra-ordinary motorhome started with a guy named Britt Palmer, who after being diagnosed with CMT (Charcot Marie Tooth Disease) decided to create awareness and raise donations by testing his GMC motorhome at Bonneville Speed Week. Britt said it best, “Instead of letting CMT slow me down anymore, my team and I intend to build awareness for CMT by “GOING FAST”.

Custom GMC Motorhome Photo Gallery


This all started with a eBay purchase of a beat up GMC motorhome for a few thousand dollars. As you can see from the photos the motorhome was striped down and rebuilt for speed. Britt worked with, and Lucra Cars to create a one of a kind sports car in a motorhome’s body. The photos show a ton of structural, aesthetic, and powertrain improvements. The structural cage and racing seats in the cab look very out of place. Stop and imagine a motorhome flying by you on the highway at 120.838 mph. That is the speed they achieved at Bonneville which was a little under 8mph short of breaking the record. Apparently the conditions were not ideal as wind was a concern. Anyone who has a motorhome knows what a good gust of cross wind can do to your rig while traveling at high speeds. Good news though, the custom GMC motorhome intends to come back in 2014 and give it another go!
