also if the unit has wheel wells stand on the floor next to them as they have issues leaking and wrotting floors there as well as the floor in front of the ramp gate, if the gate leaks it wrotts the floor there too. if the unit has a fiberglass cap look in the front corner of the unit to make sure there's no signs of water as well. look at the leaf spring shackles as they are seldom checked and the cheap Chinese shackles used on all most all of them wear quickly and then let go on the road. even on that small of unit replace the tires with 10 ply!! **** the ramp gate and stand inside to see if you can see daylight, a lot of the ramp doors were built too weak and have been known to bow then leak! and all that otrfun said!!
