Looking for solar suggestions

There was a reply to my post but its not showing up?

Your described usage is so low that you could simply install a single battery Group 27 or 31 and a single 100 watt panel and basic controller from Home Depot or from one of the online sellers (www.solarblvd.com) etc
and you would be well past covering your charging needs if there is any sun at all. A maxxair or fantastic fan if kept in one of the lower settings uses less than one amp of power, and LED lights use very little as well.
You likely could place the battery on the tongue and if your tow vehicle uses a 7 pin plug, let it charge the trailer on the days that you move, and on the days you dont, simply start the truck and then connect jumper cables to the trailer battery for a half hour and get whta you need.

Cargo trailer, poorly insulated, can be hot as hell or freezing cold.
Cold you can fight off small propane heater without 12V draw, just make sure of adequate ventilation.
On hot days/nights you might want to run 12V fan on High, about 30-40 AH over 12 hours, together with LED lights. For this reason I would get battery group 31.

100W solar might work, if augmented frequent charging from truck alternator. With 10A solar controller.

From our experience for a grp 27 or 31 true deep cycle you will want about 160 watts of solar in full sun. That said if battery life isn't important 80 to 100 watts will work.

My son wanted solar to keep his batteries charged while in storage plus some. But I found 2 80W used panels which is more that you asked about.

100W might be adequate for you but consider a 160W 12V panel from Solar Blvd as you'll have room for more power or just plenty when it rains all day.

Here's my son's install. Click here.

BTW Shipping solar panels is expensive due to their size so add that cost.

Here is a complete 100 watt kit for under a $150 delivered.

Thanks everyone! I no longer own a pickup, Ford Escape which is reason for light traveling. 4 pin setup. Got some reading to do! The brand packages are helpful. Was looking at one( Renogy) but as always some sketchy reviews regarding controller.

Because they ARE sketchy :).
Renogy put entry-level controllers in their kits, controller brand varies. Connectors also vary, some people get better Anderson connector and some get flimsy 2-pole plug.

If you are set on a portable solar, this is different from permanent flat roof install. People with portables benefit more when they stay put most of the time - 100W portable works as 140W flat panel because it's tilted, but portable won't get you any charging on the road. Renogy sell 100W portable "solar suitcase" that is convenient to use and is overpriced, compared to kits that are not "suitcase" type.

OTH, if you go permanent flat route, consider making that "flat" install with few degrees slope to shed water and debris. Doesn't matter to what side, it's only few degrees. Tilt it to the back, for better aerodynamics on the road.

All these kits have basic off-brand controllers that might suit your needs, but sometimes it is not just basic but poorly made and stops working. You can upgrade it later.

I went to a site link and am looking at 2 80 watt panels solar synergy from Solar Blvd.Trailer on order but I think they will fit(comes with roof vent). Will take suggestion on tilting slightly back(1 1/2* like a drain pipe!)Although its going to depend where I park sometimes. Need more info on controller. There is a 6 amp controller by Morningstar. Panels say 5.36 amp short circuit current. Not really sure how that applies to controller. Hopefully customer service can answer questions. Also these will be wired in parallel, not sure if I splice the wires together or do they have special connection? I am learning.
