any regrets with a longer TT?

Thanks for all the responses. Since 1998 we have been part time campers approx. 3-4 weeks per yr. going all over eastern half of USA & will go full time or at least 6 mos./yr when wife retires in 2 yrs. We plan on going west & exploring. Up to this time with our 32 footer, we have run into a few navigating problems at gas stations & restaurants, especially busy restaurants whereby you turn into parking lot off of a busy street only to find an extremely difficult situation where we got out OK but afterwards wished we had chosen a different place. I realize 3 ft. longer is not a huge difference, but surely there is an upper "sweaty palm" limit. Perhaps everyone has his own comfort level.
