I finished putting the boxes on the bed tonight.  I got some stick on LED lights for the inside of the boxes, they are bright, but I do not know how long the sticky will last.  I have to wait for the swingaway jack extensions to come in.  When I bought the camper they were $200, now I need another pr and they are $269. I was not happy.  I have to put the extensions on the back because the flatbed is 11 foot long and the camper is only 8' 6''.  I will be able to cut away an area for the jack to swing back within the bed.  That should keep it from getting damaged. I will rewire the camper plug to a 7 way rv style.  The male was $4.69 the camper dealer wanted $45. I cut the hole for the female in one of the boxes.  That way I can use one plug for the camper and the gooseneck. I am goig to line all the boxes with 3/4 plywood to help support the load  I put in them. I figure to spread the weight over the whole bottom of the box.
