I'm wondering what doing modifications does to warranty. I've tried to do a search and haven't had much luck. Worried that doing mods will void warranties.
What mods? What warrenty? If your asking about add ons to a motor then, uea, it could void a warrenty. If your asking about adding a shelf inside, I see nothing wrong there. Unless you saw thru a stud or something structural.
I'm thinking like solar or hard wired surge protection. My trailer is 2017 Grey Wolf 23DBH. It's prewired for solar but I'm reading that it's not that great. That's a whole other discussion.
Solar? Four screws thru the roof seales with lots of Dicor wont leak. Mine have been up there 12 years with narry a drop of water. The wires can be threaded down next to one of the vent pipes if necessary, again sealed with lots of Dicor.
