Well good luck with your decisions.. I have wanted to get a slide-in by my leafs are shot! Just a normal sleeping platform on the passenger side and a dog bed with hitch bike rack for camping.
Looking at a Tepui Tent from a friend, would love the space in my bed for more storage! I will be camping out of my truck for a couple months this summer.
Any and all coolers would be a great idea. A lower thermostat and a possible electronic twin fan set up. Is anybody running the URD 7th injector at all?
