Using the same scale that Craig Holland used (before it became a political war on private or commercial), I came in at 13080 on the Front Axle and 21720 on the rear axle.  Now I have to figure out how to lose about 1k pounds on the front end.  Spec is for 12,200 on the front and 24,500 on the rear.  Are there any other 10S owners that have issues with weight?

I hardly have anything up front at this point...(no cabinets, no flooring) maybe the 800lb generator in the front bay needs to be a smaller generator in the rear?  I think I need to get behind the dash and pull some existing stuff outta there.  I am pretty sure that I am going to sell off the Webasto system in the front bay as well.  We are all electric and I cannot see boondocking in the cold enough to warrant having the webasto system for heat.  We dont ever plan on being in a place that has snow for more than....well....ever.

Lose the spare tire?  What else can I shave off to get my front axle weight down?

How bout it Oakie?  What do you weigh in at?

on what size tires are the axle ratings/GVW ascribed to....if you have 22.5 or 24.5's there may be a difference in the maximums that you are saying....are these limits off your applicable tag ?

I guess the first thing I would do is get reweighed at a different scale, if that's possible.  I had to do a search on Eagle 10, it's a long 40' bus with only two axles, and the rear axle is real far back.  Not sure what I would do - start by doing an inventory of everything in the bus by estimated weight and location, that will let you create a spreadsheet that will tell you exactly what the effect of moving or eliminating something will be.  Anything in front of the front axle is 100% or more (leverage effect) on the front axle, anything between the axles is shared on a percentage equal to the ratio of distance between the two axles.

Why remove the Webasto?  It doesn't weigh that much and if you are all electric it would be a nice addition for another heat source and the other uses it has.

Not terribly overweight-just change the front tires from the 14 ply to 16 ply that are rated at 13,300lbs and be done with it. Axles, brakes, bearings, etc are way over rated. I used to run at 13,500lbs all the time on a 12,000lb front end. Except for bottoming out a couple of times, never had problems with anything. I ran 16ply 11R-24.5 that are rated at 14,600lbs. Good Luck, TomC

Hi Sean,

I am assuming at that weight you had a full tank of fuel. With it being located in the front bay that puts a lot of weight on the front axle.

and if you can move anything from the front to behind the rear axle it add lift to the front; twice the bang for the buck.

Classic problem with the 10s was weight distribution that was reason they never were that popular with the revenue crowd you have your work cut out for trying to lighten the front end on a 10s, the MCI 40ft 2 axle bus ran into the same problems
