If we're talking about a camper van then I must say the Webasto diesel heater was a bit of a life saver on our first couple of camping trips last year... minus 4C overnight in early May down at Charmouth, woke up as my head was frozen to the tailgate, sorted within minutes.
I'm going to say the LED card has been overplayed a bit on this thread as realistically the H4 can be made to perform better than stock with various combinations and levels of intervention from brighter bulbs to headlight surgery and fitting a Morimoto bi Xenon projector , I butchered the headlight caps on my camper and stuffed kick arse LED H4 lamps in, obviously not as fantastic as the legendary VW LED headlight but just under £3k cheaper.
