I have been wanting to add a spot to store my wheel chocks, and assorted pieces of wood that are required under the stabilizers when setting up on uneven ground. Here is my solution. I mounted an 8 gallon action packer tote to the tounge on the pup. I had to start by moving the propane tank a little to one side. It had been mounted in the dead center of the tounge. This was a simple matter of drilling two new holes in the angle iron the tank holder is bolted to. I mounted the tote to the tounge using two chunks of angle iron. I painted them black to match the tounge. I drilled through the bottom of the tote, the angle iron and for the two bolts on the left of this pic, into the c channel on the trailer tounge. I used large fender washers to spread the load out and keep the bolts from pulling through the bottom of the tote. I used plenty of caulk to make the penetrations water resistant. Here is a side view of the mounting. I think it turned out pretty good. I have been using this type of tote (the larger type) to carry all my camping gear for nearly twenty years, and have yet to replace one I hope it stands up to the junk thrown up by the tow vehicle.
