I was able to find the exact tank for my 2012 trailer. I purchased the unit new to my dismay the tank had already been repaired once by the factory or dealer prior to me aquiring the trailer.
I ordered the tank on line and swappede it out with the leaking tank.
I consider it a 7 job on a scale of 1-10.
No too difficult but you do have to remove underbelly and wrestle old tank out and new tank in but it's doable.
Contact manufacture or decent dealer to inquire about replacement tank.

I repaired my FW tank a few years ago on a TH I owned. Previous owner tried to use silicone to repair....wrong! Removing the silicone took longer than the repair! I used a plastic repair tool I purchased from Harbor Freight; it worked perfect! It's like soldering plastic. Just take your time, go slow, and it does work. Never had a leak again!

Sorry to not get back about this sooner. I have a guy that has a place that will spin weld it for $150 if I take the tank out. I have another trip to the mountains next week, so I will pull the tank when I get back. Thank you all

Sorry for not getting back sooner but I wanted to make a trip and make sure my repair was sound. My spin weld guy flaked out on me so I contacted a RV dealer near by that was recommended and he welded it for me. $200! I wanted a new tank but I guess they repair them all the time as some had advised me here.Little pricey but what isn't these days?
Thank you for the help!

the vast majority of plastic fresh water tanks are a material that is easy and best fixed by spin welding. Holds up great. In fact in these tanks most of the fitting that aren't molded in are spin welded at the factory. Most repair shops that do spin weld repair have an assortment of spin weld patches on hand. Basically the patch or fitting is spun against the tank and friction melts the junction, stop, let it cool and it's welded together.

For black/grey tanks, most are ABS which again is easy to fix, but instead of spin welding, solvent welding is done. Basically either use ABS glue on small cracks or use abs sheet material to bridge the break and solvent weld.

$200 is a bit steep. But if it continues to hold it will be money well spent.

I dropped the tank cut a hand-sized hole in the top so could use glue on the inside of crack. Then patched the hole on the top well enough that nothing could fall in.

Speaking of fw tanks...I was filling with water before setting up camp and couldn't get the water to go in as usual...it burped and splashed back like never before. You could feel air being forced out the inlet past the hose. Hmmm. Crawled under the coach and found the overflow tube, sure enough a mud dauber wasp had plugged it. An ignition key for the truck (old school) was the right size to dig the mud out. Filled fine after that. I guess that's another thing to check when readying the coach for travel.

As water goes in air is forced out the overflow tube, unless it's plugged.
