I love the Newline New O2 .. works amazing !! I put a shut off valve and cap on my pump out dump hose. You know the minute you unscrew that cap whatever is left in that hose will give ya stinky finger !!
Nice job, great install, as far as the spray in liner , when you get theses vans new I would recommend to have them totally stripped in the cargo area where there is only metal showing , floors, walls and ceiling then spray the liner everywhere floors, walls and ceiling that way you have a true water tight seal
Some type of a rack on the inside of the van ceiling would be nice to use that space up there, to store eg, the carpet cleaning wand, tile cleaning tool, ec, keeping them out of the way up there, instead of storing them on the front of the side shelf.
