Not a modification to the trailer per se, but something I have always wanted to make - a pad for the tongue jack that also acts as a flagpole socket.
A little background...
Because the tongue jack post descends between the permanently mounted spring bars on the ProPride 3P, we don't use a jack foot. MIL and FIL just traded their TT for a class C, and they gave us this jack cone.
Because the cone is 8-1/2" wide at the base, the closest lumber size was nominal 2x10. I figured on a jack pad with a 12" permanent stack for the flagpole and 12" of removable, stackable pads for the cone. The stackable pads would be loose for now but would be made interlocking with short lengths of dowel on the top of each pad and corresponding holes on the bottom. Here are the rough drawings and lumber calculations next to the meal plan on the kitchen whiteboard.
The extension tube of the tongue jack pad is 1-3/4" and the flagpole is 2-5/16" at the base. The closest hole saw I could find was 2-3/8"... I don't think 1/32" of space between the OD of the flagpole and the ID of the stand are going to cause any problems.
I measured the distance I figured I would need between jack foot and flagpole and drew the base in Visio to get all the dimensions down.
Off to Home Depot for two eight foot lengths of pressure treated 2x10.
I needed to cut 14 square pads - seven for the flagpole and seven for the tongue jack. I set up and tested a stop block on the mitre saw, then cut the pads.
I marked and measured the centre of the seven flagpole pads and drilled them out with the 2-3/8" hole saw. I used the same hole saw to align each pad with the one below it while I screwed them in place.
I got a little creative and made a handle from a scrap of 2x4, rounded over on the router table and stationary sander, then counter-sunk and screwed in place.
Ready to go! It comes camping with us this weekend... I'll report back on how it worked out.
