If I'm not mistaken, the battery bank is now sitting right forward of your drive axle on the passenger side, which if I read your printout correctly is your highest weight discrepancy. I think your 4 corner weights are just fine. I personally would not be worried about that amount of difference.

On my coach, the battery bank is under the drivers seat area and just behind the front left steer and it is a good deal heavier than the front right steer.

For 2017 on my aspire the house battery bank is located midship in front of the drive axle which helps with the weight distribution, but now I am having trouble understanding the Goodyear inflation charts. The chart as well as the stamp on the tire itself shows a max tire weight of 6940 on a dual tire configuration. My corner weights on the drive axle are 8520 passenger side and 7120 drivers side. Am I looking at that correctly? Does this indicate that I am overweight on the tires for that axle? 8520 is a long way from 6940. Hopefully there is a ride height issue as was suggested.

Does not make sense to me that on a single tire configuration a higher weight is allowed than dual. [emoji848]

Not sure why Goodyear would do it, but I suspect you need to double the (D) number to get the correct wt to psi.

The tire weight max for the duals is for each of the two tires so the load max on each side is 2x6940. Or divide the 8520 in half and that is the actual load on each dual tire. You could run the minimum pressure on all the rears (80psi for the Goodyear), I usually just run 85-90psi and don't worry about temp and atmospheric air pressure variations.

Also what floor plan do you have? My '13 RBQ had a similar discrepancy, much heavier on the passenger side due to fridge, galley, pantry, washer all being on that side. Never presented any real problems though. The 44B is balanced more evenly.

We have the B model. Thanks again for the input and help with this. Much appreciated.

I might be inclined to get another drive axle weight before I did much.

With a "B" model then the drivers side should be the heavy one. Drivers side has the fridge, washer, and dryer. Yours is the exact opposite. Warrants further inversigation.

Ok. I will get ride height checked. Shift some of the heavy stuff over to the pax side and then re weigh as mx chief suggested. See where that goes. Thanks for all the help and suggestions from everyone.

Did you mean drivers side? I thought your passenger side was the heavy one?

Yes you are correct. Passenger side is heavy side. I did mean to say shift weight to driver side.

As a comparison our 44B loaded for full time use is 100 lbs heavier on the DS tag and 600 lbs heavier on the DS drive as compared to the PS.

Explanation I got is that single tires get more cooling than duals, so the weight allowed for a given pressure is higher for a single than a dual.

Reason for asking is what Don brought up, seems if the relationship between ride height/alignment of tag-steer and front is off, you could have the same issues others have commented on both here and on SOB's recently.
Me? Don't know up from down....just a thought. Seems inter-related somehow.

I don't notice anything in the actions of the coach. That said, this is the only RV I have driven for any period of time. The weights were done at the Spartan factory after the ride height was corrected. The tech said that the weights were well within spec.

At the time it was weighed, the fuel and water tanks were full, and the waste tanks at about 20% each.

What tire sizes are on front? My Aspire has 295/80 Goodyear G670s with a load limit of 7830 @ 125# which is the max inflation. I am assuming yours are bigger or you would be well over the limit.
