In November we bought our 377 RLBH Jayco North Point 5th Wheel. We've been through 11 states so far and about 2500 miles. Loving it!
Only thing we've had an issue with is refueling. We try to get diesel when we are unhooked at the campgrounds so we don't have to maneuver around... but on the road it can be tricky to find a station you can get in if they aren't a truck stop. Also truck stops have been a bit of a pain too. Truckers will just pull forward a little and then go get lunch so your left sitting there for 30 minutes.
We travel with a 3 yr old boy and the Mid bedroom and loft have been great. It has a lot of bells and whistles that have spoiled us.
