I'd have to vote against the StableLoad Quick Disconnect. They are sort of a pain to engage/disengage.
I should have gone with my old trusty timberins.
StableLoad Quick Disconnect:
1) lay on the ground (dirt/mud/wet)
2) have ratchet and extension handy
3) Pull carter pin with fingers or pliers if required.
4) Tap pin out since it doesn't always slide out.
5) Insert ratchet and turn into position aligning hole
6) drop in pin and hope hole is aligned.
7) Insert carter pin
8) repeat climbing on the ground 3 MORE TIMES for each StableLoad Quick Disconnect. Last time I needed to engage them, it was wet and dirty out. Sort of sucked. You cannot engage while the TC is on the truck also. I've loaded and then forgot and had to take the weight off the truck and engage them.
They suck enough for me to probably sell and get timberins next summer.
