Has anyone out there installed a catalitic heater in their rv??? We recently just purchased a 34 ft bighorn model 3070rl and I want to put in a catalitic heater near the island. I want to know if I drill straight down near the existing heater vent will I run into wiring ect.? With the closed undercarriage you can't see what you ae getting into. Please help. ( i am thinking the installation would be on the curb side of that center islel.) Any help would be appreciated..
