I hope this placement is OK. I didn't see a more appropriate place to put it.
I currently keep my Safari 25 in my driveway, which has a right angle turn up to the garage on the side of the house. I have been backing the trailer into its spot with varying success, and some damage to plants in a bed near the driveway.
A couple of weeks ago I put a receiver on the front of my truck, primarily to mount a bike rack. Last week I got an adjustable rise ball mount and a tongue jack caster wheel (rated at 1000#) and yesterday I used them to park the trailer.
I backed the trailer into the driveway until it started to get difficult. Then I threw some sand on the driveway to provide a slippery surface for the tires when fighting each other in the sharp turn. Prior to unhooking the truck I replaced the tongue jack foot with the caster. I disconnected, turned the truck around, and re-hooked, using the caster to limit the load on the front suspension and finished the hard part of the job. WOW!
What a difference. Moving the coupler with steering the front end of the truck hardly moves the back of the truck at all compared to how the front end moves around when coupled to the rear hitch. I think the sand helped limit the stress on the tires, too.
So if you were thinking of getting a trailer mover, ($1000 and up, I think) you might want to consider a front receiver, adjustable ball mount, and a caster.
