This thread got me working on my Deals Gap 2-stroke meet prep. I can fit my H2 and Ninja 250 in my van, but also taking the DT100 would cause me to have to use my trailer just for it. So I'm upgrading my cheapie trailer hitch to a 2" receiver type, and getting one of the hitch mount carriers like near the top of the link in the original post. The sub-200 lb DT100 should travel just fine on the rear carrier.
Thanks for getting me going on the prep, Old Lemon!
