Under Trailer Fix-for son-in-law

[Sue46]

Son-in-law is thinking of buying a TT Grand Design. He is questioning the validity of a repair made by a local place. There was a leak from the black tank(connection needed to be tightened). The repair person cut out a 24x24 section of coraplast(I assume), and the foam insulation. Did the repair and gorilla taped everything back up.



Do you think this repair will hold up?



We have done repairs like this 10 years ago but the long term results are a bit fuzzy in our minds.



Thanks

The Gorilla tape will fall off in time. But you can just put better T-Rex duct tape back on.

It is pretty standard to cut 3 sides of a square for access leaving the 4th side uncut to act as a hinge. Be sure to leave the "hinge" side towards the front of the trailer so the wind does not get under it as much. Check tape yearly.

Thanks for reminding me. We did that 10 years ago and it workd well

They make underbelly tape for this purpose that works better than duct tape.

That underbelly tape sure is pricey. I would stick with Gorilla tape and check it once in a while. You never know when you will need to go back in.
