Actually more. The gearing in Rev is lower than in Low.
However, some units are prone to breakage with massive loads in reverse. Can-Am's will break the live shaft that runs through the engine cases to run the front driveshaft if you pull hard in reverse in 4wd. That is a very expensive fix, involving removing the engine and splitting the cases.
Suzuki Samuri's will blow their birfield joints in reverse in 4wd. I used to wheel a Samurai, and I still shudder when I see someone pulling backwards.
I have a 4500lb winch installed on an Extreme Max Products receiver hitch. I haven't had time to actually do the wiring install yet, but I bought a quick connect plug for the winch cables, which will be mounted up under the box.
I'm great at buying stuff, but horrible at actually committing to installing them!! Work all week, then ride on the weekends seems to be priority!
