I have 900 watts of solar panels (3x300) and lately, after a night running the fridge, batteries are down at least 25% but by 9 AM they are fully charged. Way too much solar for the summer, but I suspect just right for the cloudy winters.

NOT true we did it for 10 months off grid. Obviously we did need to get water and dump at different places that worked out for us.

05 Monaco, Signature 525 Hp Cummins looks like I have a little house on the prairie.

I think most could get by with 600 watts of solar and 6 batteries and be fine even on the biggest of coaches. Of course no A/C but otherwise its only up to your holding tanks how long you could go.

Is it really possible to be 100 percent off grid such as to run my full size fridge/freezer, lights and TVs on solar? Lights would be off most times and I wouldn't travel much, just to different camp sites every few weeks over summer. Thoughts on going completely on solar?
"Off-grid" generally means nothing constantly plugged in to your RV. And as long as you have plenty fuel, propane and water then plug-ins are not needed. With at least 600 watts of solar then electricity is not a problem and you can still run your A/C's with the generator. The only time I plug in is when I need A/C 24 hours a day to save generator fuel which can get more expensive than RV park fees.

You can likely locate spreadsheet tools or create one that includes all of your loads an duty times to determine your power needs as well as panel capacities but also note they only output full capacity with almost direct light so being flat on the roof may degrade output.

Batteries have a lot of weight and if building from scratch investigate other options such as lithium power and marine 12 volt ( compressor type) fridge.

Depending on where yiu will be traveling a Swamp cooler could be enough cooling or as many homes around here have done due to our dry area have both SC and HVAC.

On warm days cooler does the job and when it cannot cut it the ac is used.

Another poster had asked about a unit for rv use so there may be some options.

Also consider adding insulation to all sides as well as an insert for the front window.

The heat load is what determines the how well climate is controlled inside to just like current homes if yiu are starting from scratch then request additional insulation be placed wherever it can and look into having a portable barrier that you can place on the dash to cover the window if needed to reduce heat load. Can be plexiglass to allow view but blocking heat is the goal.

If money is not a problem and it is a custom coach. One could do a high amp hour lithium battery or batteries and be lower weight than lead. This also enables high voltage battery bank and charger/inverter although most lithium packs come with there own charging intelligent system. I would think configured correctly one could run a small bed area A/C as well. Just a couple high dollar thoughts.

Yes, except in the summer. When I retire, I am heading for the mountains.
