I just recently had a similar idea to run everything off a remote like that. For me not having a weatherproof unit was a deal breaker because I wanted it under hood and didn’t want to run anything inside the vehicle cab. I think if you were using it inside the camper though it would be a cool solution.
In the end I went with a Trigger 4+ which allows me to control driving lights, compressor etc from inside the cab (using the RF remote) or under hood, then I can use the app or remote if I am inside the camper and want to turn on things. This worked best for my use case.
Yeah I actually saw a review of this on YouTube last week it’s pretty cool. The problem For me is I just have nowhere to put the switch panel at. I have an off-road and we don’t have the sunglass holder like the sports an SR5.
