Use quality connectors, I used Pex in my trailer I built from Scratch, and never had a leak in the 7 years i owned it and I installed all the tanks and water lines.

What type of connectors are decent quality? I'm curious since I have been putting off some plumbing work in my rig, as a crimp connector worked loose, so am considering Flair-It fittings.

Yes, excellent choice. That is what i used. i could pressure up my system and return days later and the pressure was maintained ensuring a tight fit. Be sure the tubing is

inserted completely in the fitting and tighten accordingly. I have had to remove some fittings once and they sealed fine after that. There is also a new clamping tool

with steel rings you can use for piping, if you purchase that be sure to use the ratcheting tool they recommend. Be forewarned that to remove the rings is difficult. I ran

a water line to wifes honey house from the water heater and these suckers hold. The old brass fittings with screw type 'worm' clamps are obsolete in my book.

90% of my trailer build project came from PPL in Texas. great parts inventory and pricing is nice.

Michael65, sorry, but in my opinion, any plastic welding will never work, especially because of the extensive damage your tank suffered. You will need to replace the entire tank replaced. Here in California, were I live, in Ontario, there is a factory which manufactures and sells tanks of all shapes. You will need to remove the old one and get the dimensions. They can custom make one for you, but it will not be an exact duplicate. Several years ago I bought a waste tank from them for my Class C, and it cost me around $150.00, I last checked their website and the prices are still relatively low. Someone else on this forum might be able to suggest another manufacturer closer to where you live.

You'd be lucky to find one anyplace. Before you buy new...you might want to look up" plastic welding" in your area. Maybe you could find some place to replace just what got tore off and maybe a cheaper price than a entire new tank. I would know before hand what replacement cost would be before driving all over to get bids on a plastic welding job. And maybe the type of plastic used in 1975 can't even be welded? Also if you have more time than $$$ I think the "bus nuts" page used to have some info on making your own tanks.
