I hauled 2, but side by side, both facing sideways for the valves, but that was on a 16' gooseneck trailer, Infact I had 3 that way. I think you could run one facing side ways, the other rearward. Just run an ellbow off the sideways one, then a T as you get to the other one, with the side outlet facing that other valve and maybe an elbow to face towards the valve, then a ball valve facing rearward and a cam lock or a PVC union with an O ring to attcah the next hose headed to wherever you are sending the sap. Based on my experience I strongly suggest you top off one tank before you pump into tank #2. That way if both are not completely full you have less sloshing in the tanks to affect the driving. I used to remove both (or all 3) caps, then just open one inlet valve at a time, as that got full all the way to the top, I closed the valve, opened the next and repeated. If I was filling 3 that trip, I then opened valve 3. More often, however I only did 2, and the 3rd had 75-100 gal of permeate in it. Then when the first two were done being pumped and if the ground tank was empty as I often was, I turned the pump around (a WX15 Honda) connected a reducer, a potable water garden type hose with a spray nozzle on it and I opened the drain valve on the sap tank and washed it out. As long as you do that right after the tank is pumped it rinses out very easily. Maybe you could somehow get a 30-50 gal tank to do the same. Infact When I filled my tank for wash water I usually got 3-4 washes befor it was empty, so a 25-30 gal would likely work as well.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
