Motorhome weighed - Tire Pressure to set
Could someone double check me on my air pressure? I could not find a weigh station to weigh all 4 corners, but I do have front and rear weights so far. Loaded the RV for travel. Front: 6,540 lbs ...

I don't know why people say you need to weight 4 corners, just load RV even on all sides and just weight the front and back axels, that is all that is needed..
I call BS on weighting 4 corners, not needed unless your motorhome is leaning for some reason..
100% untrue. Very few if any RV's are evenly weighted side to side. While the difference may not be enough to dictate different tire pressures, oftentimes it is. My RV is nearly 1000# heavier on the driver side, due to bedroom slide and kitchen slide both being on the driver side, resulting in a 53.5/46.5 weight bias. The weight bias is built into the coach, yet it does not lean. Assuming anything about an RV's weight results in over or under pressure in your tires.
When I was weighing rv's with drive on scales it was not uncommon to find motorhomes with as much as 1.800lbs difference from side to side loaded full time rigs. Even brand new rigs sitting on the dealers lots had as much as 800 lbs spread from side to side without one item added by the new owners. Knowing those numbers is important to know what tire pressures are needed instead of guessing. You could guess wrong.
