We were in a similar situation as yours. We race quads throughout NC and SC and sleeping in the enclosed trailer on the air mattress was getting old fast. One night a cold front came through and we thought we would literally freeze to death. Absolutely miserable.
The hauler needs to have the ability to self sustain an entire weekend.
30+ gallons fuel is a must on hot weekends with two ACs running. We never use the pumping station because our quads use race gas. I'm not running the generator on race gas just for convenience of using the pumping station. Some Raptors have two separate fuel tanks. That would be nice.
100 gallons of water is our minimum. That way, we don't have to limit showers. I wouldn't mind even more water like a Voltage holds.
Separate garage is a must.
Things we don't like:
Like Oaklevel said, I'd just as well have a manual awning. You can adjust them. Plus if the toy hauler is leaning slightly to the left, the awning quite often will start to unravel but won't come out. Its just a mess.
Our half bath in the garage is a waste of space. I wish it was a closet. Not sure why everyone touts the half bath and it seemed like a good idea when we bought the camper. But for us, its just another black tank that has to be cleaned out. We rarely ever use it.
12' garage is OK. 14' will be mandatory next time. But two bikes aren't as big as four quads.
