I agree with the front-end weight concern. I had an 1981 Toyota 4X4 truck that I added a Warn brush guard and 6000lb winch to. The extra weight ruined the front suspension over time. I suggest getting a removable mounting system then you can take the winch off when not in use to save the front end, keep the winch from long-term exposure to weather, less tempting target for theives and save a little gas pushing that extra weight down the road.
I'm looking for a Hella light mounting solution myself. I am getting a towbar mount installed on the front (for towing behind the RV) and was considering adding mounting brackets for some Hellas.
