Nice. Wish I knew shower came in black... Good luck I remember the feeling cutting that First hole....Lots of deep breathes.. Just a tip make a template the size and tape on then step back and take a look. Contoured lines of van are deceiving.
All I need are some tasty waves, Lynnski, and I'm fine.
Lots of double checking things and lots of trimming on the inside. There are two layers of metal that will separate but in order to get the trim plate to seal you have to cut away the metal from the inside. Easiest way was a angle grinder and tin snips. Just to be safe we took the piece of metal we cut out and stuck it between the two layers so we did not cut into the outside of the van. Also used a sawzall for most cutting since a jigsaw did not have enough length in the blade to go through some of the areas.
A friend of mine did the cutting, I think it is easier when it is not your van, that's probably why he is smiling and I was stressing.
