Re: Axle and spring location
I'm guessing that the trailer in question, is the one pictured? Normally, I and most here would suggest moving the winch stand back about the desired length. However seeing that the stand appears to be fixed, bringing the axle forward a foot seems pretty drastic to me. I might think about going forward, at most 4-6 inches.
Keeping tongue weight on the vehicle is what helps keep the trailer from becoming a violent hazard on the road. Personally, I would leave the axle where it was.
