I know what I'd do if it were me, build a box on top of it and fill it with all my stuff for the drive out to Co.
I do realize that not everyone has the knowledge, tools, or ability to do that, maybe you could find a box to go on top of it, or possibly know someone capable of building you a removable storage on top? Might not be so expensive once you figure in the cost of a haul. It is something that can be done, I have helped my dad build several while growing up. Stake bed trailers, he would just drop 2x4 s into the stake pockets, secure them, and build a box around the vertical 2x4 s.
Not every trailer will lend itself well to this, and make sure you don't build something that will come off on the interstate and kill anyone.
We can't always agree, but we can still be civil to each other.
