As the title says, I claim no originality on these ideas, but I would like to take a moment to brag about putting the whole kit together.
My old trailer came with a nice platform made out of pressure-treated lumber. It was too small for us, but it was part of the stuff that got transferred to the new trailer.
I built a larger replacement out of Trex:
The boot brush is pinned in place. The platform's depth allows it to slide easily through the trailer's door for transport.
I flip it over onto a piece of rug to protect the floor.
Then the real fun. All of the pieces I need to set up when we first arrive are kept in the bottom of the platform:
You can see the tire chocks leveling blocks, level, stabilizer wrench, pad for the tongue jack and the pipe for the WDH bars.
The last stuff to stow and the first needed upon arrival!
I'm in the process of making a decent set of 4X4-chocks to replace the bricks. (the first attempt was so bad, there are no pix).
