One thing for sure - it won't get any easier if you wait. 66/65 and we spent 6 months in a 35 foot DP visiting 16 states and 6000 miles last winter. No issues setting up or unhooking. Even managed to climb up on the roof and do some leak repairs. Just do it. If you get a 10-20 year old coach, you won't lose much if you need to sell in a couple of years. We bought our first just to see if we liked it and to come up with a "must have" list for the next rig. Kept it for a year and sold it for more than we paid for it. Just cost me the parts and maintenance I put into it.
