My 100watt panel from solar blvd came in today. Its bigger and heavier than I'd pictured. I'm not in any hurry to install it. Don't even have a controller yet. Not prewired either so I'm not even sure how to do the wiring.
I'm considering using these for the install

and wondering what you think of those?
"Not prewired" is what I would deal with first.
Make sure you get a suitable controller.
Do you want to place the panel on your roof or store it somewhere and only use it when you get to camp? If the second you can easily drill through the side of your camper and have a plug for attaching a cable. The panel can be out in the sun while you are in the shade.
If you need to be on the roof, think first of how you are going to get the wires up there and what kind of pass through the roof skin you are going to have. You don't want to mount the panel and find the wires coming up in the wrong place.
Are you going to use the system in summer, winter or both. Up North, in winter, panels need to be angled toward the sun to get enough volts for a full charge. I find I can do that with a roof panel by facing south and dropping the front lift panel on the pop up. But that may not be what you had in mind. A flat roof mount will work well in summer or in southern Mexico but may not cut it in December. But in summer you may not want to park in the sun to charge your batteries.
I am using both options. I have an easy to take off roof mount system. The roof pass through goes to a plug that is under the panel (there is barely enough room for the plug and I am praying it does not scratch the sensitive backside of the panel). I also have a plug mounted on the side of the camper and a 20 foot cable so I can place the panel on the ground (propped up).
Finally if you go with the roof mount look into the On-Stage loud speaker stand (hand cranked extension pole) described elsewhere for roof lifting. It is very easy to use and will take away all your concerns about the weight of the panel (I have 120 watts)
