We have had our 3950 for three years now and do some weekend stuff but mostly use it for 3 week or up to 4 month stays. We take it to Tucson from Idaho every year. We don't have kids with us but when they do visit the extra garage beds and overhead beds are handy. You know what they say "it will sleep 9 but 2 is the best". I have had dirt bikes, 4 wheelers and a street bike that we take with us on most trips. When stopped for more than a few days, I unload the toys and use the garage as a laundry room, office, and junk room.
The toy haulers are not insulated like the regular large quality RVs, so they are a little harder to heat in the winter. We have stayed in ours in the middle of January in Nevada with 6 inches of snow. When hooked up to external power I use 3 portable heaters to keep her warm.
After I grow up someday, I will probably want a regular big long nice rig for the extra sized living and dining room. Ours gets a little cramped with more than two.
We pulled it with a 3/4 ton Chev duramax but switched to a 1 ton dually Ram and it is much better. Duallies make a big difference.
