Im helping my mate fit out his brand new vauxhall vivaro van, he has a 750 ltr upright tank, and its going to be a three man system.
Ive cut a hole in the side of the van for the skin fitting and fitted the metal box for his outlet ports , this had to be fitted length ways due to the wheel arch being in the way.
scary when I cut the hole , I used a 4 1/2 angle grinder with a 1mm thick disc, went through it like butter. the hole was 6 3/4 " long x 4" high.
