It only took me 20yrs to get where I am today Chris, with a few hiccups along the way.
Tom, when I use the B50 & pup to do north side, I'll dump both boxes on the fly to spread the dirt. Won't need to do much dozing & the B50/pup will do a great job packing as well.
Wiskybilt, I'm using a 4ch FM radio with that Mammoth & still use the +1 control unit too so the limit switches are still in play for up/down stops. The dump is on a separate ch from steering. I'll have to look tomorrow how I plugged the rx leads into rx...
I can dump on the move, but not at full throttle or dump will stop.
