Welcome to myswag, what sort of camper do you have or looking at?
I have a Cameron Canvas camper trailer. Have had it for about 5-6 years now and goes where ever I tow it. As it is a fold out camper on a off road trailer I'm adding to it constantly both inside and out with a new pull out home made kitchen, storage box, spare wheel holder at the front and gas bottle holders.
Next on the list is a storage box for various things like tent pegs, ropes, ect. plus some sort of storage box some where on the outside for the awning poles, cos there a pita at the bottom of the trailer.
Like everything around here is a work in progress.
