The northern tools transfer pump; I have. It's too weak to suck thicker oils; the tank mounted transfer pump works better but is still too weak to suck the thicker oils. In August it still took me 30 minutes to fill a 55 gal barrel with it.
I am not sure where you are going in the US; but I'd imagine you'll go through all climates.
I just recently picked up
one of these pumps from tractor supply. So far so good in the cold SE Michigan. I can fill a barrel in less then 10 minutes.
What I have done is attached a wand made out of 1" PVC pipe to the suction hose, at the top there's a ball valve at the other end there's a 2" strainer to help block bigger chunks.
In order to process 60 gallons, you'd have to have two tanks or one large tank with a baffle in it.
I think the nomad system would be very easy to duplicate using some standard fuel transfer tanks, just add a few heat exchangers, and a couple of ball valves with plenty of insulation. I'd put a sock filter (I think it's size #1, the 4" width) inside of a 4" pvc tube and pressure filter from one tank to another.
Then again this takes alot of space up if your going to put one of those "bed campers" in the back of your pickup, on top of the additional weight.
Honestly, IMHO It'd be quite a challenge to come up with something; but from the experience I have so far with collecting/filtering/burning 100% veggie; I don't think it'd be worth the effort to invest time and money in it for on the go, at least not with what I'm picturing.
I'd instead would probably invest the money in a propane kit to help boost fuel economy. I'm filling 20# cylinders for $12 and people say you can go over 1000 miles before refilling a 20#'r, if adjusted lightly. If you get an extra 5-8 miles to the gallon, I'd think that would offer a better ROI with something "on the go" vs the time pulling off the highway, finding a source, processing the oil. I think you'd end up burning up the veggie quicker then you can replenish it. My superduty will suck up 100 gallons going from Detroit to Dallas and that's only a 18 hour drive.
Good luck.
