I never thought about using it for nascar. I have always wanted to reserve a spot about a year in advance and do the whole tailgating/bbq'ing and watching the race. I also have a suzuki samurai that I have hauled in my toyhauler quite a bit. Not only was it a little on the heavy side for that trailer, the door wasn't really up to having that much weight on it. Also, a pain in the neck to get out of after you get it inside, and a huge pain to crawl up underneath and strap it all down. Now, i've got a towbar that i'm gonna make the mounts for and just tow the sami 4 down. It only weighs 1900# so it doesn't even need brakes. When we go camping up north in flagstaff in a few weeks, i'll tow it behind and have a way to go explore the forest if I choose to.
