RE: dry weight
This is perhaps one of the most misunderstood things about RVing. And, misunderstanding it can cause problems of safety, mechanical problems, ruined vacations.
First, the basic formula is dry weight plus carrying capacity equals gross vehicle weight rating.
Dry weight: This can be obtained from a brochure but the problem here is it does not allow for any options. For example, if an air conditioner is optional it will not be in the dry weight. If it is, it is in the dry weight. If an optional air conditioner is added it will be about 100 pounds for example.
Carrying capacity: this is the weight that the springs, tires, shocks, frame, etc will carry. Technically, while it is a combination of all these it is generally the lightest component that will determine this rating.
Gross vehicle weight rating: GVWR - This is the rating of the dry weight and carrying capacity added together.
Often the trailer will have a paper sticker in a cupboard or on a door and it will generally give two of the three.
If it gives the carrying capacity and the dry weight, the total will be GVWR.
If it gives the GVWR and dry weight the difference is the carrying capacity. If it gives the GVWR and the carrying capacity the difference is the dry weight.
Now, the problem is this. If for example you had a dry weight of 5000 pounds and a GVWR of say 8000 pounds. This will result in a carrying capacity of 3000 pounds. This is becoming quite common now with better brakes, axles, etc. The real weight of this unit loaded with propane, food, water, clothes, etc will likely be around 6000 to 6500 pounds tops. People are passing on units their truck can tow by only looking at the GVWR. They are penalizing the manufacturer for building a better unit. People generally have about a 1000 pounds in their unit.
Can you trust dry weights? Not always,. The Recreation Vehicle Dealers Association sets guidelines for it's members to adhere to. Manufacturers such as Arctic Fox do not belong to it nor have the required sticker. This is why an Arctic Fox weighs a lot more than it's disclosed weight. If you don't believe me weigh one. They use the weight before the slide is added!
I hope this helps you in your purchases!
