The rooftop A/C units weigh less than 100 lbs, which isn't a terribly heavy load, but it us usually more than one person can handle easily. In addition, a person plus the A/C would exceed the capacity of most ladders, either one mounted on the RV or an extension ladder. Two ladders and two people working together might walk it up the ladders if the unit is strapped to a 2 x 4 for the people to carry while climbing.

If you can pull up to a 2nd story deck or similar structure, you could move the unit from the deck to the roof on a couple of 2 x 4s. Another strategy would be to hoist the unit with a block and tackle from a tree or structure you can move the RV under and lower it on to the roof.

Somewhere here there is a thread showing the clever method used.
I don't recall the details, but it was something like leaning an extension ladder on the side of the coach, securing the new AC unit to a piece of plywood wider than the ladder, hooking a rope to the plywood and simply pulling it up the ladder.
He said it was a fairly easy one person job done that way.
Perhaps that person will chime in here.

That would work, but I'd suggest putting cleats on the sides of the plywood to keep it from sliding off the sides of the ladder.

Rent a cherry picker. Probably a worthwhile investment

I used a rope, extension ladder, and a helper. I got on top and pulled while the helper guided it up the ladder. It was easier than I thought it would be.

Thank you to you all for your suggestions!

I am replacing both since one has recently been limping and not cooling well after running a while and would pull too many amps. It would start out at about 15 amps, then as it continued to run, would go up to 20 amps (the problem is the compressor and definitely not dirty filter, coils, etc, or bad capacitors)

Both units are original /20 years old, and since I need to replace the limping unit, I decided to just go ahead and replace them both. Perhaps I should wait until the second units fails, yet simply prefer the thought of not having to deal with the second unit if / when its time comes. I am also "upgrading" to 15,000 BTU units from the original 13,500 BTU units and they are currently on sale at PPL Motorhomes in Houston for $591 each...

I'd suggest just replacing the one that's bad. The other could have a lot more life left in it. Years ago I bought a used MH. The original 11 year old air conditioner worked fine, but the cover was in really bad condition. Instead of getting another cover for an 11 year ac, I decided to buy a carrier ac as a replacement. At the time they were considered to be a really good ac, mine turned out to be not so great. Well my new ac lasted less than two years before it stopped cooling. I had to go out and get a replacement for my replacement.

Scissor lifts and cherry pickers in my area are reasonable at ~$120.00 per day delivered.

I've rented the lift a few times for the electrician to pull a new circuit in the new RV garage.

If you haven't used one in the past get them to show you how to operate it and explain safety procedures, watch the pinch points.

rope it up still in the box and using a wide extension ladder, pull it up with one guiding it up and one on the roof pulling. 5 min job....Pad the ladder where it rests on the top edge on the roof. If possible have a 3rd person steady the ladder footings on dig small holes for the legs.

If you want to do it yourself, I'd go with a rented material lift as the easiest route. You can probably get one delivered for around $100.

If you are intent on doing it yourself, an extension ladder and come along will get it up there pretty easily.

After I found out my local RV dealer would install the AC for $220 I took the RV over to them and they had it replaced in about an hour.
