Get a 2 person tent. Also a 4 season construction. We were in Wyoming last November My KUIU Storm Star was the only one that withstood the winds. 2 person size gives you more comfort room.
I might as well always figure a 1 man tent is too small for 1 man and a 2 man tent is really a 1 man.Having said that, if I was wanting to do what you want to do, I’d put a canopy on my truck. Build a little elevated platform and put a mattress on top and have storage underneath. Get an easy up to cook or whatever underneath.
