Bumping this thread, because i have similar questions. If anyone has any input, i would appreciate it.
wjs0311, I have a similar setup as you did (GX390, 3 reels, 12V pump), and i am going to try to set it up in a Ford E350 van. I have a 275 tote, but may not use it right now, because my PW is direct drive and i dont think it will pull from a buffer tank. I'm using 55 gallon drums for SH and mix tanks. Maybe 5 gallon jugs for downstreaming.
Did the van setup work ok for you? What did you do as far as the floor situation... did you coat it? Also, did you make a divider to go between the cab and the back?
Thanks for any advice... im brand new to all of this and this will be my first rig. Right now i was thinking about stacking 2 reels at the side door, but that's as far as i have gotten with the planning.
