Default Replacement air conditioner choices

My 15k Dometic AC isn't cooling very well lately. I did all the "fixes". Cleaned filter, checked for air leaks, cleaned coil inside and outside, not freezing up. It has been in the lower 70s, so it should be doing a little better. I thought of having freon checked, but read that most newer rv units don't have check port, and it would be more cost effective to replace unit rather than have a port installed. I also ran it at 104 volts at a park with bad power a while back. With that said, if I have to replace it, I'm undecided on what to go with. All the major brands claim to be more efficient and better than the others. Any input would be appreciated.

Get the one that will plug right in and save yourself alot of time and headache. I replace one in my old trailer the same time my neighbor did. He got a deal I bought the direct replacement for $40 more. Put them both in the backhoe bucket to lift them to the roof. Mine was cooling within an hour his took 2 more weekends. Just my .02

Did you buy a extended warranty for the RV? On my last TT I had a warranty on it it would not blow cold enough and they replaced the whole unit for the $100 detectable.All I did was call the repairman told him the problem he ask me for the policy # and the numbers on the unit 3 day latter he called to set up a appointment to replace it. I have found on a RV the cost of the policy normally pays for itself on a older RV.5 years of owing it the policy cost $1,800 the total for repairs was $2,460 (AC, Refrigerator,Hot Water Heater,1Axel)

On the three RV's I have owned they all had Coleman A/C and I have never had to repair one. That is my anecdotal recommendation, granted not very scientific. I may have just been lucky!

I replaced the AC yesterday with a Coleman Mach 8. Wow, what a difference. Blows harder and colder than old unit ever did! I'm taking the old unit to Holiday World, where I purchased the trailer(AC still under warrantee ). I have a 1990s 7500 btu AC as a second unit on the trailer that I will swap out with the new replacement. Woooo them boogers weren't easy for a 45 year old fat man to lug up and down that step ladder.

Bench test at Holiday World revealed that the AC is working properly. Problem is probably dirty coil. I told him that I cleaned the coil already. I took a closer look at it and sure enough, it was dirty down inside the coil. My attempts to clean it with a vacuum with brush attachment had made the surface look good, but I had just pushed the dust and crud further into the coil. I couldn't see this while it was on the camper, but out in the sun with the cover off, it was obvious. Hard lesson learned. I guess I'll clean it properly(with coil cleaner) and lug that beast back up and swap it out with the 7500 btu unit.

If anyone is going topside to clean their A.C. take your power leaf blower and do a good job of it. Works great.
