mystery water in under belly

[jwrenn]

Hello All,
Went on a relaxing trip to the moutains in November. On the return trip we stopped to check tire pressure and noticed the under belly insulation sagging and dripping water. I used my pocket knife to cut a small slit and water gushed out, really gushed out, gallons.
Got home removed rougly 50% of the insulation, edges were the wettest part, the middle of the camper was the dryest, the very rear was also very wet. Tool it in to dealer they kept it for a month and came back with "can't find anything wrong". I am at a complete loss as to where to start looking. Ive checked caninets and under bunks, no signs of water. Camperis only a few years old. Any help appreciated.

Might be the Freshwater overflow. If dealer didn't find any (if he looked?) then tackle the job yourself. There should be an explanation where that water is coming from (at least it is below the floor). What model unit is it?

Fill the tank with water and see if anything is leaking except overflow drains. If nothing then take it for a road test and see if there are any leaks. Also determine if there is no crack in any of the tanks. The fresh water tank has an overflow usual 2 together and are mounted on the side rail chassis. That could be the culprit too and you'll loose about a 1/3 of water while traveling. I stuck a 2" ABS pipe capped on the top through the floor upright and moved the overflow hoses in there. Some people put taps (shortcut) on those overflow hoses but I would not recommend that. When a tank is half empty while traveling there will be a lot of air movement in the tank. It has to escape and breath again.
