I have ONE more question that is related to this topic. Can you use a wood or wood/metal hole saw on the outside fiberglass of a boler?
Not having done it, I don't see why not. As you can tell from the posts, the fibreglass can be cut by many different types of blades. I have used hole saws (the kind that go into a drill like a regular drill bit) on many surfaces and never had a problem. They are similar to other kinds of saws, just round.
To answer your earlier question (I only get to review the forums once or twice a week), I always run the electrical
wires inside the trailer, not outside, from the area under the kitchen where your electrical
service is, around the back of the trailer attached to the inside of the rear dinette seats, and over to the area on the entry side where I need it, again under the rear dinette seats. On my trailer, to go from the one dinette seat to the other across the back I ran the wire under the insulation at the very back of the trailer (the trailer stop/turn light
wiring is already there), and then covered the edge with a vinyl self-adhesive baseboard moulding for floors that I got from Home Depot for about $3. It also went very well with the new lino floor that we installed a couple of weeks ago, so it covers the wire and looks nice too.
As for the electrical
service, when we bought our trailer it had essentially none, just a wire going into the trailer and a bunch of Marrette twist-on connectors to various other wires. So, I replaced the wire with a good quality power bar that has a power conditioner and a circuit breaker built in, attached to the inside of the little cupboard between the fridge
. This served the purpose of distributing the electricity with more control and flexibility, and should be safer. Not as elaborate as a house circuit box, but works very well. As a bonus, I no longer had the long wire sticking out of the trailer that had to be connected to shore power and then rolled up again. Instead I use a standard outdoor extension cord, with a trailer connector adapter for the 15 amp service when required. Works great, easy to do.
