Buying new fifth wheel

Just bought new FordSuperDuty F-250 Diesel. Looking to buy larger fifth wheel. We were towing a 7100 lb flagstaff ultralight with a 150 v-8 and it was really to much for the truck in hills and rough roads. What size weight and length would tow well behind my new truck. Don't want to get in the same situation. To much trailer for truck.

  • We tow a 2012 35ft. Crossroad Cruiser 345rf with out F250 . We did install airbags to level it out, the truck tows it well and no problems
  • I kind of did the same thing, got the 250 and just bought a 5th wheel this week.
    I want a fairly light trailer, reason being. I rather say, I didn't even know it was back there than say man this this is hard to pull.
    I think my dry weight is 8300 lbs. It pulls good but up hills you know its back there.
    I would never want the max weight I could pull, but that is just me.

    Unfortunately, you're doing things a bit bass-ackwards. Much easier to fit the truck to the trailer than t'other way 'round. As others have said, make sure any FW you're looking at won't exceed the NET payload of the truck. The only way you can approximate the loaded pin weight of any particular FW is to take the published dry pin wt., divide by the published dry wt., then multiply the published GVW by this number. Even then, depending on where tanks are, where the storage is and what's in it and how =you= load it, that final number may be several hundred lbs different. Once you settle on a few different FWs, post questions here asking if anyone has actual real-world weights of each particular one. From that, you can see how the pin wt. ratio might change with different loads.

    You need to look at your weight listed on the door jam sticker, for the available payload. You will have to figure the weight of all pass/gear that will be in the truck, plus the FW hitch.

    What ever number you have left will be for pin weight of the new FW.

    Yup, have to do the math yourself. Everyone has their own situation.

    Floor plan???
  • I pulled a 2008 37' cameo w/ 3 slides no problem. The total loaded weight was 14k. New f350 deisel because alfa 5th wheel I have now is same weight but more tongue weight.
  • Stay within the trucks GVWR.........ie: available payload for pin weight

    Look at the 5th wheel GVWR and use 20% to guesstimate the 5'vrs pin weight
    DON'T go by any posted pin weights..those numbers are 'dry weight'---actual will be closer to the 20% of GVWR
