Thanks for the feedback so far. I am kind of leaning towards a new truck and a lightly used 5th wheel. I can afford to spend whatever I need, as I can even sell my house and buy another later after I travel around awhile. I don't know how long 'awhile' will be.
As for expectations, I am not a tinkerer. I can do maintenance, I am just not a person who loves to tinker with this and that. I have two local 'shade tree' guys who can fix just about anything. I'd rather just pay them, they charge reasonably. Point being, 'reliable' for at least a few years is top on the list. I know things will go wrong based on threads I have read, just hope to keep it to a minimum.
