The Quest for Worlds Fastest Motorhome and a Cure for Charcot Marie Tooth
Update:  November 1, 2015

Thank you to everyone for your incredible support of our Worlds Fastest RV project and the cure for CMT.

There have been 4 cancelled races due to severe weather since our original run in August 2013 where we achieved 120.9mph during the Bonneville Speed Week event.   Mother Nature just hasn't wanted us to race since that time but we are patient and using the time to fine tune everything.

We are eager to make this land speed record attempt in our New GMC LSR Motorhome and hope to see you in August 2016.

The sole reason for this World Record Attempt is to bring public awareness to a devastating neurological condition known as Charcot Marie Tooth Disease or CMT.  

Please click on "about this project" or visit to learn more about how you can help.
In August 2013, The Palmer Designs GMC LSR Motorhome went 120.838 mph on the 3 mile course.  According to the Guinness Book of World Records, the newest record for "Worlds Fastest Motorhome" as of December 2014 is 141.3mph.  In order to surpass this new record we've made a few modifications to the engine and significant modifications to the aerodynamics.  We are confident that we can break this new record in August 2016.  Now we just need mother nature to cooperate by keeping our race course hot and dry.

We are seeking the World Fastest Motorhome Record to raise awareness about Charcot Marie Tooth disease (CMT) which is similar to Muscular Dystrophy, Multiple Sclerosis and ALS but not many people have heard about it.  CMT damages the peripheral nerves and causes muscle wasting, joint deformities and weakness.  Many people with CMT have significant pain and may loose the ability to control their hands/arms and feet/legs.  CMT is the 2nd most commonly inherited neurological disorder in the United States.  According to the CDC, the prevalence of CMT is equal to Multiple Sclerosis and 10 times more prevalent than ALS.  It is estimated that between 3 Million and 6 Million people have CMT worldwide.

I have this disease and my team is helping me fight CMT by going fast.  Click on the CMTA logo to the left to donate directly to the CMT Association.
