We enjoyed our 16' Bambi for as long as had it, and towed it with a Tacoma with a topper over the truck bed.
One thing you might consider with a 16-footer is that it has very limited storage space.
With a 6 foot truck bed with a topper and a crew cab with the Tacoma, we had all kinds of room for camping gear, extra luggage for long trips, the dog, auxiliary cooler, and so on. We could even sleep in the back end of the truck for back-of-beyond trips where we wouldn't tow a trailer. The Tacoma also got *relatively* good gas mileage.
We enjoy canoeing and our gear then includes canoe paddles, life jackets, and a water-tight blue barrel. We also like the desert, where we carry extra jerry cans of water and gas. A generator and (emergency) portable waste disposal tank often comes on longer trips.
So if you think about what you want to do on your camping trips, with how many people needing how much gear, and how long you're likely to be out there, you can guesstimate your cubic foot needs for storage.
