We own a 2003 Trailmanor 2720 SL camping trailer. It has an RV Products 8000 model rooftop AC. I am assuming that is an 8000 btu AC unit but can't find anything on it. I have pulled the cover and read the owners manual and about the only thing I can find is the maximum amps on a tag on the AC unit says 20 amps. I have a ton of Cabelas points and would like to use them on either the Champion 1600/2000 watt inverter or the Champion 2800/3100 watt inverter. I would really like to go with 1 of the 1600/2000 if possible because it's only 48 lbs dry weight and will be easy to get in and out of the truck. Will the 1600/2000 be enough to get the AC started and going? If not would it be better to get 2 of the 1600/2000 and run them parallel or just get 1 of the 2800/3000 watt inverters? It will be more expensive to get 2 of the 1600/2000, but if we are camping where or when we don't need AC we could just take 1 with us. My only concern with running 2 1600/2000's in parallel is that they actually have less surge power than 1 2800/3000. Please let me know and thanks for your time. The other thing I noticed is the 1600/2000 watt doesn't have a 30 amp plug in but I am not sure that will or won't change things.

Could you insert paragraphs or breaks in this so we can read it? I will come back tomorrow to see if it is readable.Thank you.

Sorry I offended you and wasted your time, but typing from a phone sometimes is a little more difficult.

Can't help you directly much.No 30 amp plug isn't a big deal. Get a thick/heavy gauge 15 amp extension cord, keep the make end, cut off the female end and put a plug on that matches your trailer inlet. Problem solved. I have a Yamaha 2400 and run a 13.5k air with it without any issues. Couple things if you haven't found in searches yet: may be able to get a soft start kit to install in the ac to help. I have heard of people running 13.5k units on a Honda 2000 with a soft start, but most people will say it's not possible. Some people limp through by starting the fan first (low high switch) then moving the thermostat to start the cooling. Breaks up the surge a bit. I have even seen kids that will delay the compressor start for a number of seconds after a call for cooling.In the end, buying an undersized generator can be a persistent pain in the arse. Best thing I could suggest would be to buy from a business with a liberal return policy and test the small one out.

It's highly unlikely that the smaller gen. will start your AC unit. It may do it in cool weather if your at roughly sea level. As you gain elevation you will loose HP and thus starting ability with the gen. Every gen. should tell you how much to derate its output based on elevation.To RELIABLY start your AC you'll need the larger unit.I would go with one larger gen. instead of two small ones. It would be easier to handle in my opinion than two gas tanks, two things to lift, stow, etc., and the cables to hook them together.

2k probably won't start the ac. 2 in parallel will, easily. 30 amp plug is embedded in the parallel kit. I was able to read your first post just fine; welcome!
