I bought two 100 watt Renogy panels and a 400 watt MPPT controler. I made a suitcase set up out of the panels---the glass sides closed on each other to avoid damage. The two panels weigh about 43 pounds. Then I have a Renogy 40 foot cable that plugs into the trailer and goes to the controller.
I found an old square PVC fence post that I cut in half longways, and lay that in the bed of the truck--to store or carry the panels, I slide the closed panels into the PVC really easily.
I fashioned some folding legs to stand the panels up somewhat when using them.
The system actually works pretty well and I have about $475.00 invested in it.
