Title: Two New Questions

I'm sure all this information is in the owner's manuals - somewhere!

Our coach specifically states tire pressure should be 120 front and 110 rear - however, is that supposed to be hot or cold? Beginning a recent trip, the Smart Tire alarm sounded because one front tire was down to 105 pounds when cold. After a couple of hundred miles on the Interstate, that same tire was 121 pounds (hot). A simple question, but I couldn't locate the answer.

Also at what outside air temperature is it advisable to plug electricity to the hitching post (engine warmer)? We've noticed that the engine starts rough sometimes when the temperatures are in the 30's, even after allowing the "wait to start" light to go out.

Thanks in advance for any answers.

Dont know about the engine heater..?? BUT..
Tire temps as stated are ALWAYS "COLD". NEVER let any air out should you check the pressure "hot" and it reads "high".

But those pressures may not be correct for *your* coach, loaded as it is.
For further information, clickon http://www.rvsafety.org (http://www.rvsafety.org) , the website for the RV Safety Education Foundation (formerly A'Weigh We Go).
Tires that are overinflated for the weight they're carrying are subject to damage from hitting potholes, etc, and, 'cause the tread surface isn't flat on the road, suffers from inefficient braking and traction.
Tires that are underinflated are subject to heat damage and failure caused by constant flexing of the underinflated tire, as well as handling problems.
There is only one correct pressure for your tires and that can only be determined by weighing the four corners of your fully loaded coach and inflating the tires IAW the load/pressure tables for your tires.
