Stop in for a cup of coffee

So for power tour my son and I are are just going to camp out of the bed. There’s several camp grounds within the route radius. I was going to order a truck bed tent but man those are expensive these days. I do have a camper shell for this truck so I may just put it on the bed. The other option would be to rent a tear drop camper for the week:
What makes the most sense is throw the camper shell on......................why spend the money on anything else?
