farmerscotty, welcome to iRV2.com. We are glad to have you join us here and look forward to reading of your adventures and experiences. You will find we are a group of fun loving RVers that like to help where we can. To repair the floor under teh ref. will require you to pull the ref. out. Be sure you write down the wiring connection points and turn off power and gas before removing ref. There shoul be a couiple screws in the back side of the ref. and some on the floor and top on the inside that must be removed. Once you reinstall the ref. be sure to use some dishwashing soap solution to check for leaks around the lp gas connection. If you can take a picture of the damage around the vent we may be able to help in that area too.
