Congrats to you on the decision to start RVing!
One of the things to maybe keep in mind since you will be gone for long periods is the living space in the event you encounter inclement weather for a few days in a row. When shopping for an RV we factor in would we be comfortable in the living area in the event of an all day rain event, etc.
Kitchen counter space is another factor for us. We want to make sure we have ample space to cook, make a sandwich, or whatever.
Everyone has different needs and I'm sure you will find the perfect trailer!
Good Luck!
