Final summary:
At this stage, it is recommended to choose to increase the RV chassis of the onboard generator at all costs. If there is a need to connect to the mains, the charging power of the mains should also be increased; you can consider installing a charging pile interface, or you can consider installing a light panel. For wind turbines, or borrowed generators and range extenders, due to stability, it can be carefully considered. I am just an RV enthusiast and user. Due to the limitations of my knowledge, the content I write may not be 100% correct, and with the rapid development of science, the back waves of the Yangtze River push the front waves, and the current technologies and opinions may be replaced one day. For example, after the arrival of the new energy chassis RV, everything needs to be re-learned and understood.
