I don't mean to be insensitive but is there a reason you can't take a trip the old fashioned way while you're waiting for the RV to be fixed? This is a great opportunity to fly somewhere or just take your car and go visit someplace new. As MH owners we always have to have a plan B. It is most unfortunate that you are having problems but this is nothing new. You will eventually get this fixed and be back on the road again.
Be as pro active as you can on expediting the repair process. Once you are sure you've done everything you can you have to move on to plan B.
My number one suggestion to people on this forum to try and help take the sting out the MH being in the shop is; Plan and save for a great vacation without the MH. Then when trouble hits ( it does for many ) you get to go to Hawaii or someplace really nice.
Start working on your plan B and good luck getting the repair done and back on the road again!
edit; You need to try your best to keep the water from coming in the RV even if this means tarps.
