K I can't wait to see what you're doing with the air line and so forth, got me wondering LOL
Seems to me you are going to have one hell of a monster of a machine when done. Kudos, to you!
I'm giving consideration to an 8 wheel rig myself, cost is main concern and Super...aka wife....may have rather profound objections to a second AATV, doh!
Are you going to, or do you have tracks for that thing? I bet that if you don't you will soon enough!
I too like a V meter more than Amp, but one or other is better n none. Good call on the oil pressure, and you may want to consider a pyro, and water temp too.
Look forward to seeing this hitch you setup, may give me some ideas...
Thanks for posting and keep it coming!
