Yeas you could put anything on the pole. It would also be a great way to get an antenna up there. I could mount it lower but that would interfer with where I put my propane tank.
I did not have a build up thread. I have had this trailer for 11 years. Here is a pic from my last trip. I have other pictures on the webshots link. I also posted some stuff here like my battery box build.
In responce to sirenmoses' questions. I have not used the sandmats. I carry tables in the trailer, shower shelter, gas,water along with a battery box. The battery box will be going on the fender soon. I also have a large locking tuff box in the front of the trailer. This gives me weatherproof lockable storage. The action packers have my stove, grill,kitchen stuff, propane, Pett toliet etc.
The water cooler works well for ice water. I put in 20 lbs of ice and 3 gallons of water. I'll add water but it will keep cold for three four days. I also have a 5 gallon military can that I put a spout on for everyday water.
I don't seem to notice when my truck is loaded with water.
