That fifth wheel's specs are found:
PTM Sanibel 3400
The 2 things that you need to look at are the dry hitch weight and the gross vehicle weight (which isn't directly listed, but you can ascertain it by adding the dry vehicle weight plus the cargo carrying capacity):
- Dry hitch weight: 2,264 lbs.
- Gross weight: 12,695 + 2,746 = 15,441 lbs.
The pin weight will *never* be less than 2,264 pounds. In fact, it's likely to be as high as 20% of the total camper's weight or about 3,000 pounds.
This is important because this weight is applied directly into the bed of the truck. You want to keep within your truck's ratings. The most notable of these is the gross vehicle weight rating (GVWR). This GVWR has to include:
- the weight of the truck itself
- the weight of any add-ons to the truck after it leaves the factory (bed cover, bed liner, rolltop cover, fifth wheel hitch
- the driver's weight, all passengers
- everything in the cab of the truck (activities if there's kids, drinks, snacks, maps, electronics, pets, etc.)
- everything that's in the bed of the truck (firewood, stoves, grills, coolers, extra fuel, toolboxes, etc.)
For reference, my family of 4 and all of our stuff (including hitch) came to a weight of about 1,200 pounds. My advertised dry hitch weight was 1,800 pounds - my actual is 2,300 pounds. My truck's GVWR is 12,300 pounds. Hitched up and ready to roll, I came to 11,500 pounds.
I'll say - off the cuff, that seems like a lot of camper for a 3/4-ton vehicle. Even a 1-ton vehicle, I'd have pause for deciding between a dually or not. I like my truck's training wheels - it gives a lot of stability to the feel of towing. (Besides, I like her big hips.)
