AC mod

This is my solution.
Costs me about $25 ,works great.

Well the kit at airswitchrv is for Coleman units, not Dometics as per your mod. Also, your link is for setups that have a wall tstat. This kit is for setups that don't have a wall thermostat.

Anyways I ordered one to try it. It apparently can be installed without any permanent modifications at all which is good in case I want to take it back out.

popeyemth, this is fantastic. I have wanted to do this mod for some time but the other mods I have seen required more work. I plan to order the relay and install this summer. Thank you very much!

Since this mod is a couple of months away from me doing, would you know if;
Will this affect the how the furnace works? I have a heat strip in the AC unit do you think I will still be able to use it?

It will make the furnace much better if you go to the digital thermostat like I did.
No more wide swings between coming on and going off keeping the temperature closer to constant.
Can't say about the heat strip I find mine to be pretty useless and never use it any more.

I thought most trailers came with this but maybe not. I run my fan all the time. I turn it on instead of opening windows and when the AC is on I leave the fan on to keep the air flow and to keep the "white noise" more constant. Have the fan and AC kick on during the night would wake me up.

Well I got this kit from airswitchrv and installed it. It works great. Nice to have some quiet time for a change without the fan always running. Regarding the last posters comment about the fan coming on and off during the night. Actually, in the evening the unit is completely quiet and then it comes on first thing in the morning as the sun comes up. Pretty slick.

Not sure about the other mod mentioned in this thread for Dometic AC's (I believe), but this one is for Coleman brand.
