Upgrading Scissor Jacks

[itat]

I used to have to do exactly what you are doing when I parked my previous Roo hybrid in my driveway. There's no other solution.

My Husky HB4500 jack had an extended reach but it was nowhere near what I needed. I made up stacks of 10" long 2x10s screwed together to place under the jack stands while raising the tongue jack and then used them under the stabilizers once it was levelled. The photo shows the original factory manual jack which I upgraded to the Husky electric jack after the first time levelling it with the manual jack! The cut tree stump came from the previous owner.

I made a dolly, 4x6's about 4ft long. Stack with those and a 2x6 to get level height. Find 4 heavy duty casters and mount right to one of the 4x6's. Lift you trailer jack with blocks and roll this dolly under A-frame of trailer. All the weight will be on the dolly. Do not use those jacks, other than to stabilize the trailer, and cut some chocks from more 4x6 and make them bigger. Hope that helps.

Just for future reference, the stabilizer jacks shown in the front of your camper are more stable the more they are extended. The more vertical those jacks get, the stronger they are. You could remove a lot of blocks in the front and gain stability.

They are stronger when they are extended, however, they are more stable when they are less open.

I don't know about the first part of that statement, but I do agree with the second part.

Their weakest link is in the pivot areas, so the closer the structural members get to eachother on that spline, the "tighter" that tolerance is. Example would be if you take the jack and put it half way down and twist the bottom plate, you will be able to see some movement in the middle from the twisting. If you extend it all the way down and do the same thing, you will not see any movement because all the structural members of the stabilizer are close together and all the spots where movement comes from have been eliminated. As for the second part, it seems backwards, but it works out that way. It's all about the directions of the forces.
