Axle capacities

A friend is looking at a 2008 Keystone Raptor 3814SS.
After searching the Keystone archived spec`s still can not find individual axle capacity for 3814SS. Looking at gross weight divided by three axles is still a guess at best. TIA.
  • Also numerous toy haulers as well as standard fifth wheels have axles and tires that add up to less than GVWR. An 18k GVWR fiver might have two 8k axles. I will not own a trailer equipped like this.
  • People forget that toy haulers aren't loaded the same as 5th wheels. As weight is added to the garage the pin weight gets lighter. My almost empty (scaled) pin weight is 3500 pounds. If I add 2000 pounds to my garage my pin gets lighter, not heavier.
  • That trailer has a dry weight of 12,045# with a dry pin wet of 2639# (22%)
    GVWR is 16,500#---wet pin roughly 3630# (12,870# on 3 axles)


    Triple axle....would hope that they are 6000# but could be 5200#
    (RV MFG. do not put axles rated for GVWR...they put axles adequate for weight carried by axles (minus pin weight)


    Crawl underneath and look for tag on axle

  • The vehicle certified GAWRs for that trailer, with dual axles will be 7000# ea..


    Using the new RVIA tire load capacity recommendations, to provide 10% in load capacity reserves per axle. The minimum tire load capacity - via inflation - will 3850# per tire.
