Looks good, not the smallest but Webasto.
Too bad that i already have a system. Where were you sooner like a year a go because i bought a Binar 5S pre-heater. Simple, easy to use. Nothing complex and does the job like a
skipper. Once had a little problem, but hey was made simple so i could fix it simple right ? . I think i will go for a year with my Binar 5S and then think to look into another one of these small badboys. 2 simple preheaters for a simple life and warm life right ?
....best part....Binars 5S
cheap as hell.
Any way i wish you the best
