I have been researching used 5th wheels for a few mo. now. My complaint is trying to determine the length of unit, GVWR of unit, if 50 amp or 30 amp. Most ads leave 1 or all of this info out. I then have to research each unit to find it does not meet my specs. I am looking for a 6 to 8 yr. old unit, 12,000 lbs. GVWR rating or lower, 34 ft. or less, 50 amp with 2 a/c, and prefer 2 slides and a king bed. Anyone know of a unit that meets those specs? If you own 1 that meets those requirements, please give me the name and manf. # so I can search for 1.
