Lots of good discussion on this thread, and I appreciate the comments and thoughts so far. Here are a few more thoughts:
Rent before We Buy - We've been around friends with bumper pulls of all sizes and 5th wheels. We're focused on amenities as we know what we like and don't like.
Class A Options - I'll keep the Mountain Aire if I want to stay in a motorhome.
5th Wheel - I'm having difficulty considering this option due to requiring a 1-ton truck. I have zero other purposes for a truck other than towing an RV (I haven't owned a pickup in over 20 years).
We like the toy haulers because of the perceived ease of loading and unloading gear, particularly at tailgates (Penberthy RV season pass holder). Dragging our stuff (tents, chairs, cooking equipment, beverages, etc.) out and back in the Mountain Aire is a drag. Fold down the back door, and we're basically ready to tailgate?
Wasting time today (maybe not "wasting", but rather educating myself) and I've cruised PPL. Here is an intriguing example:
2021 Heartland Torque T322Trailer Folks - Talk to me about generators. Yes - required? Nice to have? Or, Nope, can live without? I take the generator for granted in a motorhome. However, it's another engine that must be maintained.
