Thank you guys!

200 to 500 watts. Or more if it fits.

I believe you would be very disappointed with solar. Too much rain and snow. As you have been told AC would not be practical.

Many solar unit today do not worry about going off grid, they simple offset their bill by selling power back to the grid. You do not even need a battery bank.

Of course the grid sells you power at the retail price and buys your power at the wholesale price. In sunny AZ that is not much of a problem, in MA it would be more difficult.

Solar works well for keeping your batteries up when boondocking but total off-grid living usually required more energy reduction then most people care to give up.

Good luck

Solar panels are basically sold as a comodity these days. Watch for a good deal on a dollars/ watt basis. The larger the panel the better that ration will be. The largest panels, like are used on homes, measure 78" by 40" and produce around 350 watts. If you can fit one of those it will be your best deal. The next size down measures about 66" by 40" and produce around 300 watts. These are also generally a good deal. When you get smaller than that you're more into "RV" sized panels but the cost per watt goes up.
I would put on one 300 watt panel if you have the room. I wouldn't bother with anything less than 100 watts.
Forget about running the AC on solar. You would have to spend a fortune on panels and batteries. The weight and space requirements would be outrageous, particularly on a trailer that size. I install off grid solar systems for a living. Even off grid homes with thousands of watts of PV don't typically run air conditioning.

You're not getting it. Without a huge battery, which couldn't be charged on a daily basis with the number of solar panels which would fit on a small TT, you can't even run A/C during the day when the sun is out.

AC and Solar not compatible or practical, not even for a little bit at night. Unless you are willing to spend many thousands on batteries and many thousands on solar.

Not moving too much actually.

Move to a sunnier, warmer in winter location?

Give up any thought of running AC off solar. It's only possible with extreme effort and cost, and your small TT probably doesn't have enough room for panels to make even limited use reasonably possible.
