Welcome Gunny, I'm with you on climbing up on things to sleep...I always figured that overhead bed space would make good storage for bulky lite weight stuff.
As for climbing i haven't been in the bed of my ranger for 2yrs.. almost went out of it backwards :s and it sits a little high up [4x4 with rear overload springs] to try again right now.
There is a wide skill set and knowledge base among these folks & I'm sure that at your age you have plenty of the same to bring to the table.
Speaking for myself I'm sportin' more than a few dents and dings to the old body...nuthin' plum broke yet... but a few places are borderline. I've a friend in the frozen north [SD] who is past 80yrs with a bone on bone shoulder and I know how painful that can be.
Today is my 3mo anniversary here at CRVL and I'm still trying to catch up on the blogs...builds....conversions while trying to keep up with all that's new...... so again...WELCOME ABOARD
