1) Self tapping screws (same way 10000's of enclosed underbellies are secured at factory)
2)EnternaBond Tape....Gorilla Tape as second choice
3)Flat Aluminum bars OR just overlap the coroplast sheets at seams
4)Insulation & coroplast attached to each other makes it easier to work with when installing/removing
****5) Heat Tape????
Check RV Furnace discharge plenum for unused cut out...install a new duct and run it into underbelly area for HEAT source
We exclusively use our fresh water tank/pump regardless if at FHU CG or Boondocking.
No need for heat tape etc. RV Furnace has maintained temps above freezing in our underbelly even when temps were -19*F
