I have no trouble with stranded #8, but perhaps there are other kinds.
Distance of ground based panels from trailer.
------
Besides anything else in the way, the trailer itself is a problem for shading the panels. You want to park with the battery bank to the South to keep the panels close facing South, but this may not be possible. If the batteries are facing North, your panels will be at the other end of the trailer--how long is that?
Usually with the panels out to one side of the trailer, at some point the sun goes around the other side so you have to move the panels. Your awning and slide being out make this "worse" so that means even farther out from the trailer.
Here we are in a field with only the trailer in the way-panels about 40 ft South of the trailer. Got sun until just before sunset when the back of the trailer gets in the way, but by then the solar has done its job. Panels in a twirling contraption I made.
You should be ok with about 40 or 45 ft distance from the trailer NOT COUNTING trees or where some other guy's trailer is.
Campground site--you can't set the panels up in the next guy's site. That and other things can make it all very awkward. But it can be done--just pick your own site carefully, looking at all the sun directions etc etc.
