While you were underneath you should have noticed a square area of the belly right in front of the axles. That is the fresh water tank. If you look at the front edge of that square you will find a piece of angle iron going from side to side. On either side there are bolts attaching the front piece of angle iron to the side pieces. If you remove those bolts the front angle iron can be removed. The fresh water tanks is sitting on a large 1" thick piece of plywood, below that plywood is a sheet of aluminium belly pan.It will be sealed all around the edges. Once you break the sealer loose the plywood and aluminium should slide forward to remove the fresh water tank. It may be very tough to pull the plywood forward. Some people have had to use a come-a-long or even pull it forward using a truck. I got lucky and mine slid right out. Be careful to only go partially forward and then support the fresh water tank prior to completely removing the plywood. Make sure you disconnect all the plumbing lines to the tank first and raise the three red valves up into the trailer and clear of the plywood. the fresh water supply is across the back of the fresh water tank. It may be possible to repair it without removing the tank but soldering pipes that close to the plastic tank may be difficult.
If you have any other question just ask and I'll try to help.
We have a similiar problem, the tank leaks over 1/4 filled. The Constructor is going to pull it this weekend. We are wondering is this a common problem with a fix or do we just wait and see and we will determine is new purchase is on the spreadsheet? We will post our findings to the 73 Tradewind project once it is pulled. He has it all disconnected.

I just finished replumbing my 73 29ft ambassador. Iremoved all the old copper and went back with 1/2" pex. Much easier for me to work with and holds up to freezing better.

While you are in there with everything apart, I would replace the copper tubing with 1/2" Pex.

very rare problem with the tank

The two earlier posts are some good advice if you have pipe problems. If you try to repair a pipe and move the pipe much, you may find a problem farther up the line of the pipe you just worked on. The solider is old and will break if moved much.
One 73 that I was working on, I pulled the ply wood out of the way and filled the tank with water (only 1/4 full) once I got it supported liked described in your copy and paste. I found no leak. I could not put more water in it until I got it on the ground. I took the tank out and then filled with water half way, no leak. I then filled the tank all the way and it started leaking. What I found is, once the tank was full, it flexed and water leaked out by way of a crack in the bottom of the tank. Once the tank was empty I could heat the crack with a solider iron and it fixed it. There was no problem with the pipes at all.

The other thing worth note is, once the board was wet it was swollen up and I had to get a Come-a-long hooked to the frame in front to get it out. I thought it was going to be hard to get back in and the project took me so long the board dried out and slide right in.

I hope this helps
