RV Repair: Water leak, removing a wall, water leak

Question
I have a 1980 Layton 24ft trailer. I have a water line busted either to the toilet or the bath tub, my question is if its the one going to the toilet will I have to remove floor and bath tub to get to it? If it is one of the lines going to the bath tub i think i can repair it by removeing the furnace, any help or suggestions appreciated.  

Answer
I have no idea how your unit is plumbed. Most units are plumbed so that it is easy to get to the plumbing in case of a leak. In most cases, you should be able to get to it by removing a wall panel, or by cutting through the underbelly fabric. Again, I don't really know how your unit is put together, so it is impossible for me to say for sure.
You certainly shouldn't have to remove the tub.
I hope this helps some,
