Entry door insulation?
I've got a Showhauler conversion with an entry door that I'm about to replace the lock on. The old lock is a cheap setup with a plastic handle for the "deadbolt", and it isn't really able to support connection to a lock actuator. So I'm going to be enlarging the hole for the latch, and have a few questions you guys might be able to help me out with:
--The door sounds hollow. Is it possible that it is uninsulated? Or is it just not solid?
--If it's uninsulated, I'd want to add rigid foam insulation. Any tips/suggestions for removing the inside skin? Is it as simple as removing the trim around the edges, then peeling the fiberglass off?
--Should I install bracing around the lock to add support when I tighten the two halves? The new lock is a Trimark 30-900, and it replaces a FIC travel-trailer lock.
