I spend upwards of 3 months a year in my RV in a standard year so it's critical that I be able to work and live comfortably (and not have the wife kill me because turning on a light is too much trouble). I've been working/living like this for quite some time and doing the RV automation can be really challenging to dial in. You have to consider that you have, what, 5-10 circuits or lights that you want to control and is it worth many hours of trial and error to get it there? There is a lot more I can do if I choose but a few basic automations is enough for me. Having a Zwave motion sensor or three and a few light switches without a lot of HA programming is what works for me. At home, I need so much automation (need is a relative word), but on the road motion activated lights are mostly enough. I also don't want anything that relies on an Internet connection - not only because it can be hard to get sometimes but it's expensive too.
The Internet is a different story. Jay's spot on, an RV park WiFi is modem speeds if you can connect at all (which is mostly not). You really
must have a hotspot to be able to use the Internet. For about $400 you can get one from all providers ( AT&T, Sprint, Verizon, T-Mobile and Virgin) and then pay $60 for 5GB of data on whomever you need for where you are going that trip - which lets me and my wife work remotely for a week and still have enough to stream movies too from our home Plex system at less than 4K quality. There are some good apps for iPhone and Android to tell you what cellular service works best in what area, I use these to figure out who to pre-purchase or, if it's in the air, I get there and fire up all my mobile hotspots to see who has the best signal and then call them right then and there to refill the data plan.
