I have a VW bus that doesn't see a lot of use and with a bit of fiddling it was easy enough to run a (fused) connector to just behind the grill with a little rubber lid to make it waterproof. That allows me to plug in a trickle charger without having to open the hood. That little trick has saved me multiple batteries already.

I can use the cigerette lighter on my tt roadster's trickle charger. Does the bus have one?

I could have gone that route but it would require the cable to go into the interior from the outside so that's why I hardwired it to the front. It also helps that I park it with its nose to the garage so the wire is very short and I just let it dangle down when it isn't in use.
