Reddit mentions of Marinco 150BBI Marine On-Board Charger Inlet (15-Amp, 125-Volt, Black)

Try changing the cord or you could put a plug in the bumper like semi's have. That's the route that I went and then I also hard wired in an on board battery tender like they use for charging fishing boat batteries. The plug is like $18 and the battery tender was $30 something but damn does my truck start nice in the winter.

In fact some Skoolie people prefer using extension cords over romex entirely.

Our fuse box has a female plug coming off of it, allowing us to physically switch between sources - from battery to generator to shore power. To do 30/50 amp power is similar, but you need a lot more stuff, and is like wiring a house. I basically just added a fuse box to an extension cord. You drill a hole through the side of the bus to mount the second piece. It's pretty cool, to be honest.

Any RV owner will tell you that water is pernicious. Skoolies are the same way. You need to caulk your bus yearly - or at least go over it and look. We replaced the running lights, and did a wonderfully poor job of it, and I didn't caulk it. Then we walked on the roof, which the metal parts had no issue with, but the front of our bus is fiberglass and it separated from the metal, allowing a leak point.

Honestly, a cleaned and then painted roof (using Henry's RV paint for example) will make life very easy. You know how you can get by a couple years between coats of paint on your house? And how house roofs can go 15-30 years? Well, imagine if you drove your house around. It will need some attention before then. Just keep a can or three of silicone or paintable caulk on hand, and you'll be good.

Also, a very handy (if ugly) thing to get is butyl tape. Overpriced version is called flex seal, or you can hit up home depot for the roofing version. It's got a silvered back, and it's great at sealing holes... and sound proofing.

I no longer can put links in as words? I dislike the new reddit layout.
