Replacing rooftop A/C units is one of the most overrated (consequently the costliest) functions RV repairman do, considering the time it takes.
I'm not a RV repairman but have replaced a couple of my own, and helped others do their's.
Very simple; 4 bolts connect top to bottom; 1 electrical plug to join top and bottom; that's it.
It may be worth it to pay another $65. or so and replace the lower panel.
Regarding getting old one down and new one up; a new Mach III weighs 110 lbs.
I'm lucky, having a Kubota with front loader makes that job a snap. However,
I have used a long extension ladder, set bottom far as I can from the RV, and gradually slide the new one up the ladder (of course no problem getting old one down................)
Main area of concern, is making sure the flange around the hole in top of you RV is very, very clean. Then just follow the directions given for mounting the foam rubber gasket, and by all means do not over-tighten it.
To make the RV owner feel he is getting his money's worth, a RV Tech. might fool around and take an hour +, but if he is any good he can replace upper/lower in 30 to 45 minutes.
Once you replace a unit you will wonder why RV techs charge so much.
Good luck; DIY and save a bundle ! ! !
