Very few trailers have an inverter to provide 120 VAC power to outlets. Most with residential refrigerators have a "dedicated inverter" to operate that appliance, but it isn't used to operate any other items. The only RV's that I'm aware of that come "fully equipped with battery banks and inverters" are high end motorhomes that often are "fully electric" and don't even have propane onboard. Typically, they start in the "half million dollar range" and go up from there.

Essentially, the reason Fifth wheels and travel trailers don't offer inverter systems is the battery power requirement. To provide 120 VAC power take a substantial source of DC power. Typically only a single battery is supplied in most trailers unless the additional batteries are negotiated in the purchase. So, to keep prices down and to remain "competitively priced" most dealerships just "smooth right on over" discussing "inverter power, battery banks and the associated prices"......
