Why carry something you'll never use..:h....use the engine for air.
Since the coach is new, you need to weigh it first. Then using those figures, check the weight tables for the correct air pressure. Make sure your coach is reasonably full on stuff you'd normally take with you on a trip when you get on the scales. For now, 110 will be fine until you have actual weights, then I think you'll find 110 is way too high. I run 110 on my steer axle, 315/22.5 100 on the drive axle, 295/22.5 and 95 on the tag. These pressures are 5PSI above the recommended PSI based on my weights. The 5PSI if for my personal comfort zone....Dennis
Note: The IDEAL method of weighing is to have each corner weighed but that's expensive and not too easy to find someone who can do it. You can axle weigh your coach at any CAT scale usually found at Flying J or a truck stop. Moving companies, grain elevators etc have them as well...D
