Do you have dried residue around the coolant cap?
The head gaskets are not hard to do with the cab on. The secret (in my opinion) is to have the AC discharged, and then remove the evap housing. With that gone you've got TONs of room on the passenger side. On the driver's side the only problem is the very back stud/bolt. Buy you can either buy or make an extension that makes it a non-issue.
Here's what I would suggest. Take the truck for a drive for a while. stop, and VERY, VERY, VERY, VERY, VERY, VERY carefully, and SLOWLY unscrew your degas bottle cap. As you unscrew it, does it release a lot of gas and bubble? If so, you've likely got a head problem. And remember, don't assume it is a "blown" head gasket. It could also be you have cracks in the head(s). I had six on one and one on the other.
If there isn't a ton of air rushing out, or bubbling, look around the front of the engine from underneath. See anything wet? I had a lower hose that has rubbed a dimple against the power steering, and developed in pin leak.
