New priceing a bit lower than I thought but ..well...
A rolling wonder frame and floats for any size up to 1400 total pounds floatation ( 700 lbs of working load)
now at $2400 with 500miles del free
foam floats bullet proof coating.. alum scd 40 frame ( non folding, but splitable) , good for ever!.. and universal room for motor/pump(s) amd sluice to 24" wide any length...Usally 6-7'..
You can use this for a 4" and next year put a 6" on it with bigger engines and you never have to buy another floatation set up. also remember it rolls to and out of the water, no fuss. and OVER cobbles and gravel bars ,no biggie!
