Truck camping sleeping system?

Going to be truck camping for the first time this season and I wanted to know what is a common setup? I have a shortened bestop softtop and plan on using a full size air mattress that I already have. Haven’t tested the fit yet. What does everyone use for sleeping bags covers/blankets etc to stay warm. Expecting the lows to drop to around 40 the weekend I’m heading out. Pics of setups would be nice.

 

If you have a decent sleeping bag, you should be fine.

This thread has some good info and shows some common setups:

Search the term sleep platform, you will find a bunch of threads.
Also, “ show me what’s in your camper shell” was a thread I used for ideas.
