We found a 1997 Horizon on a Dodge B3500 frame with 30,010 miles on it. Great units, I predict you will be happy as it seems to be designed for what you want. Our unit was prewired for the Onan and I found one on Craig's list for $500 (not installed yet). The area where the genny lives is pretty small and on ours NOT water tight although the previous owner did try by blocking the wire mesh vent.
I found that trial and error packing will put a surprising amount of stuff under the dinette/bed area.
Good luck and happy camping.

I'd keep the Onan. Being able to flip the genset on via a switch, then flip the AC makes life easy, compared to having to get dressed, go outside, fire up 1-2 generators and let them warm up, then get back inside and hope they are able to handle the inrush amperage load.
In fact, I'd see if there were a way to put a 4000 watt Onan in there, so you have enough wattage to not just run a 13500 BTU AC, but also be able to run your microwave at the same time.
Topsblades - How far are you from Atlanta? This Onan 2.8 kw $1,400 does not sound that bad. I would do as "Handbasket" suggests - have your existing one checked out.
Gene, You are truly a gentleman and a scholar. I am grateful for your advice.
I am now the proud owner of that used Onan. Best of all it was in a pawn shop and the shop owner assured me that before it was taken in on pawn it was started and hooked up to a load. The previous owner assures me that it was rebuilt and rewound (?) about 20 hours ago so it should be good to go.
It cost me $800. Seems like a great deal. Once this is installed my RV should be good to go!
Thank you all again for the words of wisdom. The other day I had David and Tracy from Backroads RV make a HOUSECALL, they came to me, and they gave me the quality walk around my unit that I wanted. They also ordered a new Dometic A/C unit with a heatstrip, replaced my shower faucet, fixed my furnace and my converter (only a panel in the fuse box) and pulled my generator all for only $1200. That includes a brand new A/C unit with heat strip and inside mounting and switches, the whole nine yards. I was extraordinarily pleased with their work. David is very talented if you are ever in the Columbus, GA to Auburn, AL area I strongly recommend their work.
My previous estimate to repair the A/C was $1200 so it looks like their will be some $$ left in the budget to repair the Onan. I agree that it will be nice to be able to hit a switch on the dash and use the Microwave on a short stop.
If it is cost prohibitive that have David or his contact for generators repair it I already have a back up small engine repair guy with generator experience standing by. As a tertiary back up I have a gentleman with a rebuilt Onan that he will sell for around $900 up in Atlanta. I will be up in that neck of the woods later this week and will definitely check it out.
