I have a 6 x 12 double axle trailer, I have been running a 8 gpm hot water on the front then a 225 gal tank and a 5.5 gpm hot water on the rear with 2 high pressure reels. I got another 8 gpm washer and it is bigger than my 5.5 machine. I was thinking of placing both machines on the front of the trailer then tank over the axles, or tank front and machines over the axles. The tank only has water in it when the trailer is parked. Whats everybody thoughts?
