As long as you have enough truck crosswinds really aren't a problem, yes the wind will push a taller rig more but I wouldn't make that a priority issue unless you are a nervous driver in windy conditions. Reduced clearance is a big deal if you want to go out where trails aren't maintained for 12' high vehicles.
If you want a hard side and pop up Alaskan makes a nice camper.
If you want a nice hard side with a radiant heater check out the Cirrus brand. They use the Alde system. Other high quality campers that will work on a 1 ton SRW would be Northern Lite and Bigfoot.
