We have small dunes here. But I travel to either Idaho and sometimes Oregon coast (Florence) once a year. I am 200 lbs. I have 21" 7 paddle haulers.
Nate is sending me a cylinder and crank kit. I'll be assembling it myself. I've paid for most of it just not shipping yet. He's still waiting on some parts to arrive.
Thanks Rupp , I asked you about your setup last year and it sounded great. That's why I ordered it from Nate.
