We have a 3-year old 26BHS. One of the fresh water tanks has a small crack in it that leaks a bit (about a drop every few seconds). What would be the best way to patch this type of plastic? The spot is pretty accessible, I just want a patch that will work ... and last.

Had a small leak/crack in mine for years. When it starts to drip I just put a bucket under it. Have tried Spray on Flex Seal, various glues/epoxy. Nothing has worked. I have some Eternabond Roof tape that I'm going to try. Will post if it works.
If it's not too big of a crack you might want to try JB Plastic Weld. Their products are the best when it comes to sealing small holes and cracks. I've seen JB Waterweld used on car radiators and hold up very well.
Another option. Most holding tanks are made from ABS plastic. ABS plastic can be welded. A plastic welding kit is around $55 at Harbor Freight. Lots of online tutorials. Might be a more permanent repair than JB Plastic Weld.
