All, I recently took my trailer to an Airstream dealer in Buda, Tx (Camper Clinic) to replace a corner section of the floor. They quoted me $700 and when I went to pick it up it was absolutely horrible. We had discussed the accepted method of removing the rotted section back to the first frame cross members, notching the plywood around the original carriage bolts and sliding it in. What they did was remove the old flooring and replace the wood with pine 1x6's with some type of grey wood filler over the cracks. Additionally the technician decided to seal my trailer all around the beltlines with silicone caulking.
Needless to say I did not pay a single red cent and immediately left their dealership and hauled my trailer to another Airstream dealer in Denton, TX (North Dallas RV). I spoke with Randy (service manager) and he was about as amazed as I was at how they repaired the floor and that they had sealed all three beltlines with silicone. That's about a 100 feet of beltine in total with good old silicone. What the heck? Doesn't everyone, especially dealers know that silicone doesn't go on an Airstream?
The dealer in Buda agreed to pay the $750 that North Dallas RV charged to remove it all. At least that's one positive thing Camper Clinic did....they owned up to royally screwing up.
While at North Dallas RV I asked them to repair the floor correctly ($370). They agreed to remove old carriage bolts, use correct flooring material, OSB or plywood, and use self tapping screws in the Aluminum U channel to put it back together. When I pick up the trailer I see that they have used MDF
and that they say they notched around the old carriage bolts and slid it in. I advise them that MDF will expand and turn to mush if it ever gets wet and they say oh no, this is specially treated MDF and we will give you a 2 year warranty on the work. So I think ok, even if it does leak I'm covered.
So I drive back to Austin and spend the rest of Saturday and Sunday resealing every beltline on the trailer with Parbond (the right way). Monday it rains and low and behold the trailer leaks and the "specially treated" mdf expands and I realize oh no this is going to have to be done right, and it will probably be me that has to do it right.
This evening I decide it (new corner section of rear floor, MDF) has to be removed and I have to see where the leak is coming from. Turns out they never even notched the MDF to slide it under the Aluminum U channel. They used 3/4 inch and simply angled the edge to make it look like it went under. Additionally North Dallas RV complained about the clean up job that the Camper Clinic did stating they had just swept a lot of scrap into the belly pan and then sealed it up. He stated "but I went ahead and cleaned it all out for you and replaced the insulation". Guess what.......when I removed the floor tonight I now had both Camper Clinic's trash in there plus North Dallas RV's and I did not have new insulation. I hate it when I get lied to!
Especially when someone trys to make someone else look bad and then does the same thing. I've taken lots of pictures of both repair jobs and plan to call North Dallas RV tomorrow and request my money back.
Ok enough ranting. I need someone with a lot of experience to help me determine if I really understand where this leak is coming from. Let me start by stating my understanding, from what I can see, of how the trailer in that section (rear wall) is stacked toghether:
2. Aluminum type angle iron, with sealant between it and frame
3. Plywood or OSB flooring
4. Aluminum U channel
I believe that the seal has been split between item #1(frame) & #2(aluminum type angle iron) and that water is entering the trailer at this section.
Am I correct that those two pieces are supposed to be sealed?
