I'd be happy to share. I'm a big beiever in NOT reinvetning the wheel. Got a few things in the agenda
Battery & 12V/Solar and 240 Battery charging (and panels of course)
LED lighting (got some 1200mm LED strips that'll do the business)
A few extra 12V outlets (can you have too many??)
PSW inverter (maybe 600W)
Sheet metal guard for water tank (it's pretty protected, but hey, call me paranoid!!)
Not too much more I want to do really.
