Bangor to Crown Point, NY

I live right by 17. I wouldn't take my truck camper over that route. It's steep, winding, with multiple switchbacks that cause you to go into the opposing lane just to make turns. Every year multiple motorcycles go off that road because they misjudge just how tight some of the turns are and go too fast.

In addition to being twisty 117 is almost straight up on one side and straight down on the other. A great ride ina sports car, but not very RV friendly. I’ve been both ways many times and agree on 89 to 7. It may be a little slow at first, but after a few miles it opens up and is a fine road with lots of attractions and some great places to eat in the towns along the way. Might even be worth an overnight stay part way along.

89 to 7 isn't going to take you any longer time wise, and probably not fuel wise either. 7 is a very pretty drive through some of the best looking farmland in the country IMHO.
