first, Honda inverter generators are the gold standard in the industry. you really can't go wrong buying one.
but, you need to tell us what you want to run on it, what size is the a/c in whatever RV you have and how much do you want to spend.
a Honda 2000 will rarely run a newer 13.5k a/c. you'll need a bigger one or a second 2000 if you want to use the a/c.
if you want to run everything but the a/c, then the Honda 2000 is perfect.
since we live in Calif., where hardly any state parks has any hookups, dry camping is a way of life. we have two batteries and a Honda 2000.
