I don’t obsess over numbers (within reason). Couple things you included as important info. You’re not trucking X country all the time or at all really. With that I’d be comfortable up to 7-8klbs TT. That’s also a big TT. You want a house on wheels or a nice place to sleep and go camping? I don’t see the need for a 30’ + TT for camping trips if your goal is camping not RVing. That can drop your weight a bunch with a smaller camper.
For ease of use I’d prefer mid 20s length and lightweight but as said above 7-8k wouldn’t bother me at all. Tongue weight is not a big deal imo. That’s what wdhs are for. Plus the air ride on your caddy will level er right up.
