We've had our 2007 Winnebago Sightseer 35J since it was brand new, so going on 7 years with it. It has been a great setup for us, and grown well as our kids got older. Plenty of room for the 4 of us, and eventually started traveling with other kids who were friends as well as our 2 dogs. Still plenty of room while we travel and while we sleep. Camped once with 11 people in the rig, since it rained they all moved in. Tad cramped but still plenty of room to sleep. With the front drivers seats turned towards the back while parked it gives us plenty of seating space for games, chatting or places to just relax. That is actually a big plus over a Class C I think.
With the bathroom on board I could make long treks without the frequent stops to use the rest stop, with 75 gallon tank I could pass the pumps too.
As you found the carrying capacity of most Class C's just isn't the same. For us I needed more then I could find in the Class C's at the time so could haul our ATV trailer or boat.
As far as driving. For 10 years we made the same run to a Spring Break location to take our ATVs. So I drove it with an Avalanche/Outback, F350/Raptor Toy Hauler and the Winnebago/ATV Trailer. First few years I'd pull in totally exhausted after the 8 hour drive. I still had to setup camp, but I was just beat. First year I took the Class A I found I arrived and I still had energy, I wasn't worried about trailer sway, or any thing else for that matter. It really was a breeze to drive. The only time it's not is when I've driven through nasty winds, but nothing is fun in that case. I liked that I was up much higher and could really see what was going on in traffic. I dread the idea of not having that if we downsize to a truck or Class C.
After 7 years we may start looking for something different. The only reason is both kids will soon be in college, and they are both getting a tad big to be comfortable in the bunks. I have zero regrets going from our Toy Hauler/F350 combo to the Class A.
