2001 kiwi 23b is a leaker

Hi all
First time here. Just purchased a 23b through an auction sight unseen. Obviously got it for quite cheap and it is cosmetically in very good shape except for some leaks.
I have no delamination anywhere that I can see or feel on walls, ceiling or roof besides one spot above rear bunk door.
I found the floor to be spongey with water marks near back and front on linoleum. Pulled linoleum and yup, wet on both ends. Had some rain and found it a slow drip at socket for rear tent pole. Ripped out that shelf.
Climbed onto roof and found that the caulking had eroded from around clearance lights. Re sealed with clear silicone (sorry I'm new lol...found out shortly after to not use silicone). It rained again two days later and I have no drip or wetness in that area
I also noticed that there is quite a bit of silicone around the outside top bunk doors. I plan on removing that and replacing with proflex (which I just did around wheel wells with). Any tips on getting silcone residue off would be appreciated.
I guess what I am looking for is anyone else who has experienced this or has any pointers or places I should be looking for to seal up. I realize I prob bought a lemon but I am determined to get it right.

Thanks

Ours had leaks also, we have a 2001 23b, it leaked along the screw seam on the roof. I too caulked it until I found out that was wrong. I have since peeled it off and have used the tape which I can not think of the name right now to save my life. I bought a roll 4 inches wide and by 5o feet and started putting it on my roof. So far, no more leaks.

Screw seam on the roof? Are you referring to the seam before it starts to curve down towards the bunk? That is currently covered with a 6" wide rubberized caulking of some sorts. You removed this?

Thanks!!

I'll let 'darlingtontrio' confirm his statement, but I would assume he is in fact referring to the Filon/Roof Seam as you described above. If this is the case, I can say that he isn't alone, I applied Eternabond Sealer Tape to my front Filon/Roof seam as well.

My caulking wasn't compromised so I left it alone, prepped/cleaned the surface and applied the Eternabond over the caulking.

Here is my Eternabond roof project:https://www.jaycoowners.com/forums/sh...project&page=3

I had the same issue on my old Kiwi 17a. Found evidence of a leak and traced it to the roof seam. I caught it early so there was no real damage. Opened it up, dried it all out, and sealed it with Eternabond. That stuff is awesome!

Bob, I like the Dicor sealing. It gives it a "finished look".

Thanks all who've responded.

So far I havent really found the leak. I suspect it is from each bunk door seams as they have been siliconed and some looks as if it has pulled away.
I am going to remove the silicone tomorrow and use silicon-B-gon to remove residue. I purchased Pro-Flex caulking from my local RV dealer and will use that to re seal.
As far as the roof goes I picked up some DiCor self levelling roof caulk from the dealer as well which I will go over the existing roof caulk with.
I placed a heater and dehumidifier in it for 4 hours last night and it is slowly drying out.
Any other problem areas wit these that anyone knows of?

I was told by a former RV/Trailer repair tech that I would be asking for trouble removing the bonded floor. He said that they had an instance where the walls actually started caving in after cutting out a decent sized section. Apparently the are vacuum bonded which is what gives them their strength.

I plan on drying out the floor as best I can, applying a mold killer/preventer that I picked up at the local hardware store. Then putting new 1/4" ply down on top and then a new floor on top of that. I also have to repair the steps as they are missing and the wood at the front door is completely rotted away. May have to weld up some stairs and have some thoughts about welding a few cross members underneath to give the floor some extra support.

Any other ideas would be appreciated.

Thanks again!!

Yes, I would check around the roof mounted A/C unit. If I'm not mistaken the 23B has a flat roof and the weight of the A/C unit overtime can settle the roof a little causing water to pool around the A/C. If the A/C seal gasket is compromised moisture could get into the roof structure and travel to just about any area within the HTT.

Also, if the TT has the TPO roofing material with the fleece backing, any moisture that comes in contact with the fleece backing can be "wicked" all over the place.

How would I know if it is TPO roofing

The type of TPO roofing material in question has a "fleece" textured backing, and this particular style of TPO was used on various models in the 2000-2006 model years. Jayco during the same time period also used a EPDM rubber roofing material but it had a "smooth" surface backing.

If you remove the A/C cover from the inside of your HTT, there should some excess roofing material to inspect.

Jayco presently uses about four different types of TPO and EDPM roofing materials, none have a fleece backing.
