Here is a picture of the problem. There is a threaded fitting that is part of the tank that the water line connects to. The fitting was cracked at the joint where it connects to the tank. I'm not sure how it happened but possibly while driving down a bumpy road and it put too much pressure on the joint. I'm wondering if using a flexible pipe vs. pex would make sense?

I purchased a motorcycle jack to lower the tank and it worked great - less than $100 on Amazon.

There are 5 things to disconnect before the tank can be lowered. Large fill pipe held with pipe clamp. Small air vent pipe held with pipe clamp. Water pipe that leads to pump connects with threaded fitting. (This is the same fitting that is used to winterize with antifreeze). Two low water drains. I didn't see a way to disconnect the pipes for the low water valves so I had to cut the pex. Reinserting pex fittings in the tight space should be interesting. I had to purchase a pex clamp wrench ($60). Probably a one-time use.
There were screws, rivets, and assorted trash in the under belly. Rather sloppy I thought.

I'm now waiting for the new tank to arrive. (less than $200 from AS dealer).

I owe you a beer.
I used pex sharkbite type plumbing fittings where needed.
Otherwise I used flexible tubing and hose barbs/clamps to make life easy.
Some people paint the inside of the tank and replace the high density foam.
Use pieces of high density foam on all sides of the tank to secure it so it can't slide/move in any direction including the side with the plumbing.

Make sure your drain is located where you want it and replace it with a decent valve.

Did that too. Relocated valve to between tires and replace cheap plastic drain with this sexy chrome plated brass one.

The job is done so I thought I would send a few pictures. Some tanks come with sensors but mine didn’t. I very carefully used a heat gun to loosen the glue and a thin blade to slowly work underneath it. An RV tech told me he has 50% success saving them. There was enough glue on the back to reinstall but I added some duct tape for insurance. Test the wiring before you completely installing the tank. Also think very carefully before you cut PEX. AS uses copper crimping rings and for me they are not easy to remove. The bigger issue is potentially ruining pipe and fittings that can be inaccessible or difficult to replace. The motorcycle jack was a great help. Once I got a couple of bolts in the rest lined up pretty well. Fill tank, drink a beer, take an ibuprofen.
