Good idea, you will have plenty of power to do what you want when want. The down side is not always finding 50 amps sites. So you will need an 30 amp adapter not a big deal most of the time. But you will be limited to one A/C when on 30 amps. We have a large rv, one A/C is not the worst but in the middle of a hot day it will struggle a little.
