Sounds like me place at the top of a mountain in WV so you walk up the hill in waist deep snow, no chance of driving up there.
I'm using all automotive components. Advantages as I see it are
1. Inexpensive, you can buy just about any kind of lights, wiring, etc for decent prices at one of the many automotive parts stores around or order in bulk from some place like waytek wire.
2. Good selection to choose from, buy from automotive stores, junk yards, etc

I'm using the same mini fuses, lights, etc that both our vehicles use so my spare parts are standardized and I can swap parts around, if there is something I replace/upgrade on my truck I might be able to use the old part in the cabin.
