Clearance geometry for 2017 FB28
I have a parking area for my Airstream behind my house off a flag lot driveway - 16' wide. my problem is the angles of the road crown down to the gutter and driveway transition up from the gutter. As it exists I cannot back the trailer into the drive way without positioning stacked 2 x 12's [ 4' centered under 8' with a 2 x 4 in the gutter - 2 ramp sets for each side ] this ramp allows the trailer back to clear the top of the ramp. Then when the trailer wheels roll off I relocate them for the truck to allow the front of the trailer and the low point of the hitch to clear.
With a clear diagram of the geometry of the required clearance of the trailer I could reconfigure the concrete driveway transition as a gentler and longer slope to allow me to back in without the 2 x 12's ramp.
Any ideas will be greatly appreciated
