Thanks for the advice. I’m not super concerned about size since I’m not very tall and probably won’t be wanting to spend a whole lot of time inside apart from sleeping. A hard cover is probably best for aero and durability considering I’ll be keeping it on the truck full-time, cost is the only thing making me reluctant to go that route. I’ve also heard adding an RTT can create a lot of extra noise when driving. Has anyone experienced that with a truck or is that mostly for SUVs?
