Looking to buy a used HTT, first camper, family of 4. Rec?

You need popup gizmo bunk end covers on pups and hybrids to effectively run the ac. If not freeze up of coils.
I think in 08 most still had manual awnings.

You can’t even sit in a bunk end or nap in one during daytime unless gizmos are on top. I had them on both of my pups and ultra rare hybrid bunkhouse I had. You will have trouble towing with a Trailblazer. I had a 2008 tb with 5.3 V8 300 hp. It could not do 60 downhill on an interstate towing the htt empty. One tow from dealer and bought a truck.
