Car Trailer Width Question - Help!

Ok I hope this helps you out. I just went out and measured my stuff.
My rear tires are approximately 66 1/2 inches from sidewall to sidewall. My rear is narrowed a bit and the tires fit inside of the fender wells. My trailer deck is 81" between the fenders, and the fenders are 7 1/2 " above the deck.

So I'm guessing that if you have 76" between the fenders you should be ok. A buddy of mine has a trailer that wasn't really a car trailer also but works for his scamp. He just had to nail some boards down on the deck to roll the tires up on to be able to open his doors. Good luck!
