Real world: My FA3005 Ragen 30' fifthwheel has a 14200 GVWR running on 2x6K axles. With 4 dirt bikes, gear, food, full 150 gallon water, 4x6 batteries, 14 gallon LPG, 40 gallons gas in fuel station, 5.5 Onan. No slides runs right at 11,700 -11,900 on the axles and between 2700 and 3200 on the pin depending on potable, grey and black distribution at the time.
Got to be really careful reading the specifications, standard and options. Dry weights in specifications/brochures are units without options installed. All options take away from the Carrying Capacity (cargo capacity) listed in the Specifications.Likewise filling the potable water tank and installing batteries -you need at least 1, affect "net" cargo capacity.
On a 300x12 XLR Thunderbolt:
Hitch Weight................1,858 lbs.
Axle dry weight(calculated).8,596
Ship Weight................10,454 lbs.
GVWR.......................13,858 lbs.
Cargo Capacity..............3,404 lbs.
All this comes out of Cargo Capacity:
Fresh Water...100 gal.=.......843
Batteries 60 lbs. each.........60
LPG
Fuel in fuel station
Toys
Personal stuff, kitchen equipment, beer and anything you throw in the trailer.....
