I just ordered the Harbour Freight 12V ELECTRIC WINCH ( PART # 43331-5vga AND the their TRAILER DOLLY WITH ALL-TERRANIN TIRES. Will report back on this thread after I have it all together and working (I HOPE)......
UPDATE: Just used my new 12volt Winch and Trailer Dolly (named in above quote) for the 1st time.
It worked well above my expectations. I was able to back my 17ft. Casita
into a gravel space with lesst that 6 inches on each side, by myself. I just pulled it back a few feet then walked to the front and adjusted the direction of the traler dolly. It took a little while but all went well. With two people it will be a dream, and now I don't have to worry about backing into my Gas meter which is very close to where the trailer goes!!!!
