Who weighs?

While parked at one truck stop I watched as one RV got weighed on the truck scale. Apparently the owner talked the scale operator into weighing the four corners.
As he put first the front and then the rear wheel on the scale, the coach was LEANING way to the passenger side. Then he turned the coach around and backed up on to the scales, this time LEANING way to the driver's side.
The ONLY way to get an accurate corner weight is for the coach to remain perfectly level while on the scales. Any lean by the RV away from the scale will make the weight given useless.
If the owner of the RV I watched then adjusted his air pressure to the scale weight he was given, he drove off with all four tires severely underinflated.

Never been able to find a scale that would allow me to weigh all four corners individually. However, I have weighed front and rear axles while loaded as we typically are loaded for a trip. In my case, I found that I had good amount of headroom remining on my weight capacities on both axles.

I weighed mine fully loaded 4 corners. I go to the local farm co-op and can only get 4 corners in cold weather when the side curbs are removed. (snow plows) I have removed a lot of extra stuff since then but they have the curbs in place already so I will stick with the old ones. I was a little light on RF so just keep DW sitting all the time. We have the supposed light weight W22 and I still had 1000# to hit the limit.

When I owned gassers, I must admit I didn't pay close attention to my coach's weight. But, when I got my DP, I figured it was time to start weighing. According to my weight figures, I could be carrying 85 psi in my tires (Michelin XZA3 275x80Rx22.5) according to the charts, but I decided to give myself a little safety margin and I carry 95 psi all around. Just had a new set of Michelin's put on last week and had the dealer put 95 psi in them.

The weight of our coach changes too much for the weight to be accurate. We seldom spend more than a few days at a locations so we are constantly burning fuel(50+ pounds per hour). We also travel mostly during the Winter months so we are using our fresh water tank instead of hooking up to park water. This means that our water weight(500 pounds) is constantly shifting from the fresh tank to the black and gray tanks. Then, of course we are using our food supplies and replenishing them on a regular basis. Basically, since the weight is constantly changing while we are on the road, getting it weighed is only a temporary indication of what is going on. Not worth the hassle for me and certainly something that cannot accurately be used to determine tire pressure.

The constant change are you talking about is insignificant in the whole scheme of things.
That's why you weigh the coach when you have a fuel fuel tank, full fresh water and loaded for a trip. That will give you pretty much the 'heaviest' weight on any corner.

As you use fuel and transfer water to the other tanks, your tire pressure will be at the max weight when you weighed it from the start. All the tires on any axle will be inflated to the higher pressure for the heavier weight on the side that weighs more.

Our coach weighs more on the passenger side so I inflated all the tires on the axle per the heavier weight per the Michelin charts. I don't think anybody would want to run a tire under pressure for any length of time as the repercussions can be so expensive.

Who Weighs.. I do not recommend CAT SCALEs I do recommend a farmer's elevator or a junk yard or other place with a FLAT scale (Cat Scales are Bridge Scales).

Oh, you meant who puts their motor home on a sacle.. Well ME for one.

I went with Aweigh-We-Go find them by going to www.rvsafety.com They bring the scales to you.

No- $200 was one I found awhile ago- they wanted $250- offered 200...
I just kept watching.

Never had the DP, or any other motor home, on the scales. Didn't see any point because no matter what the scales said I was going on down the road. Weighed my F-350 once with the trailer and it was 22,500lbs or so and I pull the same trailer with the DP.....Tires are inflated to the manufacturers specs, 110lbs. I average about 12,000mi a year I think, most towing the trailer. According to some of the experts on here I do nothing right but, It works for me.

Wife and I are planning on traveling 3-6 months out of the year after she retires next year. Looked for a place to weigh all 4 corners- and found no place near, so I invested ($200, ebay) in one of these- http://www.ebay.com/itm/Intercomp-PT-300-100127-Wheel-Load-Weigher-Portable-truck-Scale-Qty-4-1-Works-/350858402936?pt=LH_DefaultDomain_0&hash=item51b0ca5c78. (Don't know how to make clicky). Figure I can weigh once or twice a year to be sure tire pressures are right and balanced.

:E That didn't come up as $200 on my end!

As an old trucker I weighed the rig not long after we got it just because I wanted to know. Not really all that critical about tire pressure. Michelin says max 90. I keep somewhere between 75 & 80.
