Family of four full-timing...RV recommendations?

Had a 28' bunkhouse, no slide, dry weight near 5,500 lbs, max weight a little over 7,000 lbs. Ford F-150 crew cab with V-8 was too little truck to tow it comfortably in Texas with gusty winds over 10 mph.

Sail area on the trailer would push the truck around if the wind was from anywhere back of the trailer.

It had a single AC right over the top of the kitchen - made conversation almost impossible in the trailer in the summer.

It was also cramped and uncomfortable for two people.
