Very soft floor in my 2006Endura right over the holdingtanks

[amman1725]

Hey all! Hope everyone had a great thanksgiving; we just got back from the WA coast where we actually had sun on Friday! First test run for the new roadmaster brakemaster system I installed for a towed jeep; It worked great! But now for the question that has been bugging me for quite some time:

The floor just outside the shower is very soft and spongy; it continues into the bathroom; I took some measurements and the soft area is right above where the holding tanks are below; Just forward and aft of the soft area the floor is firm and fine; you can feel what appear to be floor joists that run from one side of the coach to the other; they are about 18" or so apart (I haven't measured that part yet); and its spongy right between these joists; there are no roof leaks that I know of or can see any signs of; the rv stays in a covered garage when not in use; there is no evidence of a water leak from below although the holding tanks and fuel tank block most of the view; the water pump does not cycle so there is not a water line leak; the shower drains fine; the only thing that is wierd is that when we use the shower the pump pressure is not what is used to be and pulsates a little; all the other faucets work fine with great pressure; This feels like a water rotting subfloor issue but where is the water coming from? plus there are no drips or stains; has anyone else ran into this problem? I realy don't want to cut up the floor and look but I don't want my wife or I to fall through the floor either! Our dealership went bankrupt and disappeared (no big loss they were incompetent); Poulsbo RV is the new "Gulfstream service center" but we've had some problems with their mechanics not knowing crud about Gulfstream specific issues such as slide out valve assemblies etc... Thanks in advance for any info or advice you might have; this forum has been very helpful to me in the past and is the first place I come searching for answers; Thanks again, Jeff.

I just bought a 2005 ultra super c with a soft spot in the same place. Right outside the bathroom. The dealership assured me that it was a support issue common in gulf streams. That sounded like he was blowing smoke, glad I checked here. We're going to take things apart and add insulation so we will check the shower while we're at it. the dealership said they were going to add support to the flooring in that area before we pick it up... thanks for posting!

My 05 Sun Voyager had quite a bit of soft wood especially on the right side near where the rear slide meets the body. Initially thought that was the problem so I inspected the slide seals and cleaned and coated them with some "Slide Seal Restorer" even thought these seals looked fine. Sprayed with hose from all angles and could not find water.


Moved on and decided to check out the function of the side by side reefer and Ice Maker. Well the boxes chilled down just fine and the ice maker kept cycling but there was no water reaching the cube tray. Oh well left it over night and the next morning there was water dripping from the slide room. I discovered the water line for the ice maker had came off and every time the ice maker asked for water a measured amount was spewed out on the floor under the reefer and over the water heater and furnace. I have repaired all but one small area under the big slide but not exposed either in or out of the cabin. The flooring in mine is pressed wood. The areas I repaired are now 3/4 plywood. I plan to pull the bed and pedestal and replace the entire bedroom floor next winter.

Oh yea, that reefer weighs 260 lbs. took three of us. two to stabilize while I reconnected and clamped water line. I think either someone pulled on it or tried to blow too much air thru it .

You could test out the theory that the leak is in the shower wall by somehow plugging the shower head, turning on the shower, and see if the pump runs. That would indicate whether there is a leak there or not without tearing anything apart.

On my coach (and most other campers I have seen) there is an access panel on the bottom side of the shower enclosure. If that is present it is there so you can repair a leaky drain. (Hum)



If there is one then remove the cover and look in there. Try running the water and shutting the shower head down to trickle. See if there are leaks. Actually you will know as soon as you open the panel if that's where the leak is.
