2005 Fleetwood Pioneer 18T6 - water damaged sub floor

this unit has sold

The PEX is rated much higher with PROPERLY done fittings. But my experience in my TT is not all the PEX fittings were done right, that is where I has seepage problems at city pressure.

As you can see, tow vehicle power is rarely the problem these days, but payload and stability are the driving factors.

Many of the features are excellent for dry camping, which we do a lot of. With our 2 GC2 batteries we can go 4 days with no recharging (I did install LED lighting to help.

You have done a nice job on the repairs, enjoy your TT, we sure enjoy ours.

We have an 2006 Pioneer 18CK, Love it!! But I had to redo all of the roof sealant, I used eternabond tape, also I have spent the last three days digging out all of the putty on all of the corner/edge seals,, some I re puttied, some I used Dicore and sealed all of it!!
I believe Every trailer out there needs to have this done some time during its use!!
The putty dries and cracks,, the Dicore they use at the factory is a huge mess!! They must use at least an 1-1/2 nozzle to apply it with!!
I gotta say,, Eternabond has been wonderful!! I have only had to touch up about three areas that have worked loose,, and they were really small!!

The corner seals that run the height of the trailer were dried and cracked,, I dug then out and used Dicor sealant on them..

Again,, this has been a three day job just on maintenance!! Also,, over the last two years I have removed ALL windows and resealed!!!

I did have a small leak at the rear of the toilet and it turned out to be the water supply,, they cut it to short at the factory and the strain created a small leak.. I re cut and added a larger piece of pipe,, Hopefully high and dry now!!

One of the many little extras the original owner provided was a pressure reducer - some how this thing is supposed to prevent exposing the pex to full city pressure and limit it to 40 Psi (i believe) - as a guy who has a reasonable understanding of hydraulic theory i find it hard to believe - flow limiter yes, pressure regulator - I can't see it. Nonetheless, we never hook up without it.

Yeah, I don't understand this, too. PEX is rated to a much higher pressure. It may be that some RV's are still being made with Butyl pipe. Butyl is notorious for leaking fittings and such.
I've had my trailer hooked to the house system at 80 psi and didn't have any problems. I plumbed the rig with PEX and don't have any water hammer issues or leaks. I also used full-flow ball valves on supply lines instead of the cheaper 1/4 turn valves. :?

Push rivets are sold at Mcmaster-CarrBTW, nice job and good documentation!

Great work! I have the 2006 version of the trailer we purchased Oct 2005, and we love it! So many features on this unit not often found on shorter trailers. I will have to keep an eye on ours so to be sure it doesn't do the same. One thing I noticed with ours was the PEX plumbing is fine with water pump pressure, but under city pressure it immediately would start to seep. Not a big deal because we dry camp most of the time, and when we hook up I just gravity fill the tank as necessary. Someday I will try to get to all the fittings. I wonder if the your previous owners had it on city water and the joints seeped for an extended duration.

Ours has the solid bunk/shirt wardrobe over the double bed. I installed toddler bed rail, and when we travel all our suitcases go up there and the rail keeps it all in place, then tucks under when we arrive. The kids love sitting on the bunk looking out the window. I sleep on the inside, and while a bit cavelike it doesn't bug me. I have done quite a few usefull little mods over the years, one of the best beeing changing the bathroom vent for a "Fantastic Breeze" fan. Quite, relatively low power draw, and it really moves some air!

I can't believe you pulled it with a Liberty! They are pretty heavy. The cabinet sticker on ours says 4030lbs as delivered. Add batteries, propane, water, stuff, and I am sure we are at 5000lbs. We started pulling with a V8 Explorer, and when my family grew to 5 we bought the Expedition.

My black tank is to the rear with the gray just forward of it too. Now I have to root around!

I added mud flaps years ago too. Maybe that's protecting my "rear".

I shortened the shirt ward so I wouldnt bang my head on it. It was a pita because the cabinet was fastened thru the roof rafters. Dont know if you have a bunk over your bed. I took ours out and made a nice shelf. It made it feel much bigger and brighter.

I have thought about doing this exact thing with mine. The bed is like a cave with the bunk and shirt ward above it. This will probably be my next Winter project. I added a back window a few years ago at the head of the bed. Very nice for fresh air. I also added a roof vent over the bed in front of the shirt ward. Between that and the added window, it's much brighter and more airy.

S'more campers, it's looking good. Thanks for sharing this adventure. I appreciate the opportunity to get a peek at the construction in that area of my trailer. Did I miss where you isolated the leak? Was it the shower drain? Something else in that area? I'm definitely wondering about the construction difference between your '05 model and my '04 which doesn't have a drain pipe in that storage area.

My pleasure. By no means am I an expert, if you can drill a hole and have reasonable control over power tools this is a fairly basic repair.

There was no real 'leak' in my trailer, the water coming up off the tires penetrated the black membrane underneath the trailer, soaked the fiberglass and ruined the floor from the bottom up. There is a section of the steel frame that was holding the fiberglass tight to the floor, allowing the water to wick up and penetrate the chipboard.

The black pipe in the storage compartment is the drain for the greywater from the shower. How are your tanks mounted to the frame? My black tank is at the rear, then grey then white - maybe the tanks were laid out differently?

The window install over the bed is very intriguing - I find air flow to be less than fantastic in this model, I've even thought about adding a window over the couch up front.
