We had a mobile tech come and give us an estimate of $450. He would remount the tank under its angle iron then run one or two (I can't recall) reinforcing straps under all three tanks then re-fasten the belly skin.
It looks like it's covered under the warranty so we'll be reimbursed for the $250 deductible.
We have no choice but to do it...we can't leave Friday unless it gets done and don't have the expertise or the time to take off from work to try ourselves. Maybe we'll can do other less critical work in the future...
Thanks for all your suggestions and advice...
