Class C Overloaded?

Just purchased a 2003 Winnebago Minnie 31'. On our first trip we decided to go to fort wildernesses for the weekend. So we loaded up 5 bicycles on the back rack, three adults and 2 kids. Enough food and drink for the weekend. The fuel tank and propane topped off. Knowing we were going to a full hook up camp ground I left the water tank empty. I did however wanted to treat the black and grey tanks so they were about one third full. Thought it might be a good idea to stop at the CAT scales for a weigh in and much to my surprise. We were 400 lbs OVER GVWR !!!!!
We are average size people and I don't think we loaded excessively. Any one else have these issues?

  • If you have a bathroom scale have a kid stand on it take his weight hand him/her a bike and go adding all the stuff that you want to carry in the RV, deduct the kids weight and you have that actual weight, you will see how much stuff really weighs, and then start eliminating all that is not really needed.

    Also have the wife stand on the scale as every member of the family.

    NOTE: when you are going to have the wife stand on the scale recalibrate so that it is 10 pound less, you do not want to sleep in the dog house for a few nights.

    Once you have all the weights you can pack the RV so tha most is between the front and rear tires to distribute the weight rather than having an imbalanced unit.

  • The CAT actual numbers: Steer Axle 4620
    Drive Axle 9980

    GAWR Front 4600
    Rear 9460
    The other question I had is.... My rear tires are rated@ single 2680lbs or dual 2470. I assume since the rear axle is dual, the total weight the tires could Carrie would be 2470 X 4 or 9880lbs.

    So not only was the back axle overloaded, so were the rear tires.

    A dealer I spoke with once while looking at a travel trailer suggested you should stay at 80% of Max weight. I can't see how this would be possible unless the kids and the dog stayed home.
  • One reason that class "C" are over loaded is that the manufacturers use the smalles chasis for what they are building, they will use a F-350 to manufacture a 22 footer and use the same chasis just enlongated and then proceede to add all sort of goodies like heavy counters, tile, and then they add a slide or two.

    Some of the rental units that are being manufatured today are using heavier chasis as in the F-450 and no slides, you also have to consider what else do you carry in the RV, cast iron pots and pans, havy plates a whole set of glasses and beer mugs and all sort of goodies, and no one takes into account the wheigt of the persons in the RV.
  • But the real world cure just might be different tires so that being overweight will not cause a failure of the tires.

    Hopefully you have front and rear axle weights separated out
  • Welcome- what you have is quite common. Lack of cargo capacity is a frequent topic. Post up your actual numbers and you'll probably get a lot of advice.
  • Lots of people have these issues. Many (most?) 31' Class C's are overloaded. Customers want more space, so manufacturers put too much on the chassis. The factory then uses shady accounting to lower Dry Weight like making the generator optional and then adding it just after weighing.

    On the one hand, you're overloaded. On the other hand, you're not alone and you know what to look for next time.

    Fort Wilderness is our kids favorite camground, hand down!. Enjoy being able to head there for a weekend.
