Thanks for the tips. As you can see in my sig, it is definitely not a 'high end' motorhome. So adapting it to work from a cell phone would not be that easy, or so I think, even though I am a RETIRED (25 years ago) electronics/computer guy. (I haven't kept up with technology since then.....at my age I prefer the KISS method)
I like the idea of just running parallel wires to the front of the coach, but don't look forward to fishing wires. I do have a couple unused switches on my dash control panel though. I could just set the controls to A/C or heat and the desired temp at the T-stat before hitting the road and then just turning on or off from the dash.
Executive: Just how do YOU spell 'thermostat'? :B
