Too much thinking & too little working.
Not real happy with RR spikes for the feet. Contact area, 1/2" square too small, afraid that they will rip off when turning or worse yet rip the tank.
Have any of you ever made a a Pillow Block Bearing?? The ones big enough for this guy are about $150. each. Here is my plan, 3/16"x2" Steel strap, bent into a "U" shape with ears that fits around 2" water pipe. Sleeve it down with PVC pipe to fit the axles, drill a bunch of holes in the PVC to hold grease. Cut off coupling's to lock it in place. Chances are that every now and then the PVC will have to be replaced, but not a big deal.
Next, have a small tank 12" x 60", it will be mounted slightly above and forward of the big tank. 2 Reasons, a little more tongue weight. Next a spray bar will be added in front of the sheep's foot and 1 behind it. A little water may help on some jobs.
My pea brain is getting tired of all this thinking.

:laughing:
Sure like to hear what some of you think. :confused3::anyone::mur:
