The recent thread on stabilizers and levelers ran on to four pages, so rather than take it off in a new direction, I decided to start fresh. First, my '83 Burro
has been structurally modified somewhat... it had a frame-off rebuild with a heavy new floor of 3/4" or 1" plywood coated with a pickup bed liner type material fastened very securely with multiple bolts and screws to the (very well maintained) frame as well as the shell itself. In short, I now have a very rigid unit.
My means of leveling is to use a pair of scissors jacks of suitable size and capacity under the junctions of the rear cross beam and side rails of the frame. I have a tongue jack with a pad as well as one of the swing-down jacks on the side of the tongue and of course the little stabilizers that came as original equipment on the back bumper are still present.
When I spot the trailer at its campsite, I first use the tongue jack and the two scissors jacks to level up side to side and front to rear... three points making a plane. I use a simple little carpenter's level on the back bumper for side to side and on the door threshold for front to rear leveling. Finally, I swing down the tongue side jack and bumper stabilizers to simply firm up the settings I have already established with the "real" jacks, of course leaving the jacks in place. BTW, if the ground is less than solid, I use some 12" x 12" orange plastic pads under the feet of the various jacks as needed.
Now, the reason for all of this description is that after reading the thread on Parkliner
stabilizing and leveling, it would appear that I am "supposed" to be supporting my trailer at the tongue and axle
and that using the back corners puts undue stress on my frame, but at this point, that doesn't seem to be the case. Am I missing something here or is my setup with my specific Burro
going to do as well as it seems to me to be doing?
