Slide out /Underside wearing

[The_Rhino]

I just purchased a used 2011 PT 3150BHD-TE that showed no signs of previous water penetration at the dealership. However, after several days of heavy rains (causing floods nearby) with the slides both in & out I noticed some dampness in the left corner of the large slide-out. Before purchasing, I knew this was a weak spot of the Primetimes, so I have been checking the slides for wear & leaks daily.

I have decided to do a DIY fix & install the Majestic Formed Plastics product on the bottom of the slide-outs. Before adding the strips, I plan to coat the plywood with thinned epoxy. I appreciate this thread and look forward to info on what part numbers to buy, etc. In-turn I will do my best to share my experiences as well.

What makes you think this is related to the slide underside. I'd suspect a window leak first.

I'm all for adding the wear strips to protect the wrap and underside wood. But are you sure this will stop your leak? Check caulking, window and rubber seals / wipers.

I purposefully examined my (used) 3150 at the dealership near the end of a heavy 2 hour downpour. (Good idea for all - Even NEW TTs were leaking & not because vents or windows were left open...) With the slides closed, there were no leaks that day or signs of any previous leaks.

With the slide extended at home, I stood in heavy rains (again) and watched the water roll over the edge of the slide-out and across the fabric weave. The water didn't drip-off the weave until about 2" from the edge of the slide. This is the same spot where there is some wear on the fabric where it touches the roller.

Just to be safe, I re-caulked the outside edges top to bottom of both slides & will see how things fair in the next rainstorm. Again, no problems when the slides are in, just when they are extended.

However, if a slide side-window is leaking, how to I re-seal a window seal? Is there a product that can be applied underneath the rubber seal, etc?

X2 I have seen the same on my unit.Only I dont have rollers. Are you seeing water on the inside?

After a day of rain with the slides out the carpet was damp in the very left corner under the dinette. The dampness extended about 1.5 feet in both directions from the corner and the pine 2x2 in the left corner started to show signs of leaching-up water from the floor. Immediately I put a fan on it and ran a dehumidifier.

The next day I caulked the exterior corners just to be safe. It hasn't rained heavy since, so I won't know if I fixed it. I want to add the plastic runners underneath because IMO the water is coming-up through the fabric weave - because the weave actually holds the water longer vs. a drip-edge... If I get in over my head I will have the dealer look at. The dealership is just 10 minutes from work & they have treated an uncle & some friends right.

It has been 7 weeks and my 5th wheel is still in the shop, waiting on PT to ship parts for cabinets damaged from a window leak and defective slide out seals that were eaten by the wardrobe side gears. Regarding the Darco tape on the bottom, I have spoken with Rick at PT several times and it seams they will only repair the Darco tape and adjust the slideouts in the hopes I will go away. They obviously will not admit to a poor design, because then they become liable to repairing thousands of units. The plastic shields by Majestic Formed Plastics may be the answer, but PT will not participate. I have emailed Majestic for a part number and a reference for where to purchase. I will post again when I learn more.

I received an email back from Dave Rheinheimer with Majestic Formed Plastics the other day. I haven't had time to call him, but he did confirm they make them and that he could help me out. His email is drheinheimer@majesticformedplastics. His cell phone is (574) 320-4883. Not sure if he was going to point me in the direction of a supplier, or let me order directly from them if I chose to.

Nice work bigjohnd, that's good info!

Tiggerdad, Im still working on getting a part number. Should be a easy task...NOT!
No one knows or is telling me what the part number is....I was told when they find out I will know.

Strips are installed on 1 of my super-slides today.

I will post pics later.

When you installed the strip did you have to left it or just start to bring it out when it lifts? Also how did you attach it staples as the factory does or use double sided 3m tape?.I'm sure that will end PT problem but they do not want a recall, so they won't approve it. To me thats terrible they use it on Rockwood and Flagstaff units..

[BigJohnD]

This should be RV industry wide. $120k Mobile Suites, same problem. Excel uses Darco underneath I believe. Not sure if there's is tearing as I haven't looked at one in a while, but I would imagine in time they will. Not sure what it'll take. It's almost like they want the things to tear up. Best word I can think of at the moment for this design, DUMB! I find it interesting our dealer won't even go back with the OSB slide floor with the Darco. They use a 1 inch plywood floor with a black coating on the bottom, and STILL use the glides. There is a better way for sure. If yall get bored, check out the duro slide floor from parkland plastics.

Think they've seen the problem before? Wake up FR, here's some answers for you.

My dealer did the job, but I did talk to the tech after.
No jacking of the slide was need. He opened it enough to remove the screws on the trim. Pulled back the gaskets and slid the strip under.( still having a hard time getting my head around that)
No screws or staples used.
Dont understand how he got them in between the wear bar and slide w/o buggering the 3m tape. Tech said its not a big deal. Took an hour for 1 slide.

I will be keeping a very close eye on how they hold up and or any problems.

Thus far Im pretty darn impressed and everything works nice.
Will post pics later.
Dont think the strips with the 45's on them will work on my system.

Game 7 tonight GO HAWKS!!

Please post some pics etc Platokidd. I'll be really interested to see how it all went together.

My rig is headed back to PT in July for a list of items, slide wear is one of them. I'd like to give them this suggestion and see if they will use it.

They don't add any bulk to the bottom of the slide? I am concerned about it potentially rubbing along the bottom.

Strips do not touch the leno flooring and I use the slide slicker over the carpet.
I think it would be fine with or w/o slicker. (didnt try, but I will next time its opened up.)
No bulk to speak of, goes in n out smoothly. I did put some 303 aerospace on them today for lubricity /and I dont want to create wear to the wearbar, thus I will keep a close eye on things for sure!
PT is well aware of the slide wear parts that were installed on my unit.

Platokidd, where did you buy them and what was the part number i need to get these on both my slides. Thanks

see post 298 n 309

Only a item number.

My dealer got them from PT

I just purchased a 2014 PT Lacrosse 329BHT and the bottoms of the slides look exactly the same as they have from the start I did not see any wear issues from the start but will keep an eye on them and talk to the dealer if/when I see the issues.

Here's how my dealer and a very smart tech dealt with my request for a long term fix to this issue. The white strips are uwhm sheet cut into strips. Screws are counter sunk so no contact with flooring and black adhesive is 3m marine grade Sikaflex. I have also ran a bead of pro flex sealant along the Darco edge. Rv tech was VERY familiar with this issue across many brands. I am quite happy with this solution.
