Cold tire pressure is at any ambient temperature when the tires have just sat for several hours. However, the sun beating on a tire will have an effect of a pound or two so it is best to do it when the Sun is not beating down on it. Just remember that the Sun will make a difference and if the Sun was not shining it would be the same as the other side of the rig. Also on the duals, if it is a little cool out the inside dual may be a pound or so higher in pressure because the heat from the MH from being on the inside may keep it up a pound. Nothing to worry about. If it is within a pound or two just ride on it and a mile down the road they will both be equal

I have left my rig stored in a roof covered only storage area for two months and when I check the tires to leave they are within 2-4 pounds of when I left them. I leave them like that. Drive it to the house, load it up in a couple days, check the tires before we leave and everything is back to normal. I also check my tires every time we pull up site. One time in the last 3 years in the mountains did I have to put about 4 pounds in each tire, and then we we got back down to deflate them again. Every other trip we have been on the tires have maintained the pressure i have put in.

One exception - a blow out on an inner dual required a lot of air to be pumped into the new tire.

My onboard compressor tops out at 132. I installed an in-line bleeder adjacent to the air chuck, if I need to bleed the compressor down, the bleeder is just a couple inches from the inflator.

Start to finish the onboard compressor is quicker than my previous Porter Cable 150 PSI electric compressor.

I can add as much as 4 or 5 lbs to each tire without the need to cycle the compressor.

It probably works better for as my tires don't run as high as yours. Depending on loading I run 110 to 115 front and 90 to 95 rear.

None of the above. Mine's built in to my coach. I have an air tap at the front of the coach, and can inflate my tires to over 110psi.

Besides I'd rather run a 1 hp electric pump than a 435 HP diesel pump in a campground.
I have to have 120 psi in my rear tires (XRV-1 singles). At 69 I don't have time left to wait for the on board compressor to top off those tires. My PorterCable 6 gallon 150 psi compressor rides in a spot I nornally don't use and it can top off any of my tires in less than 2 minutes. It's worth it weight in blood pressure pills.

Yup, same here.

Anyone with air brakes should have a connection to hook up a air hose to the air system. I've got two hoses hooked together, I think I've got like a 100' reach. I've helped many smaller RV's with airing up, rafts, bicycles, even my corvette from time to time. I sold the old portable

I use my on board comprfessor and have it set up similar to Sdennislee. Split it 3 ways - 1 to a digital inflator, 1to a psi guage to monitor the coach system PSI and 1 to a bleeder (handle operated) Start DP and set cruise control to get a fast engine idle. Bleed as necessary to get the DP compressor to cut in for more pressure and you have no problem getting to 115 or a bit better on mine. I don't know how slow it might be getting to 120 as my dp compressor cuts out at 120. Will try that though and see. Anyway I am hoping not to have to carry a separate compressor. I don't mind if it's a little slower.
