At the risk of sounding like a broken record (you old folks will know what I mean) ;); three items must come together.
First the floor plan, you have to like the layout. Only you can decide that. As my DW found out; because of the built-in furnace, water pump, plumbing & electric lines, it is not so easy to rearrange the layout.:(
Second Tow Vehicle, it is not how much it can pull that is important; it is how much you can load into it that is important. With family, toys, add-ons and other stuff you will exceed the payload or Max cargo limit long before you exceed what the TV can pull. That means you will over load the TV suspension before you exceed what the frame can handle.
Third Finance, RVing should be fun not a burden.
In my opinion, all the units are only as good as the dealer. They are the ones that have to stand behind the product.
We bought a 24 ft. Dutchmen with slide. The biggest advantage is it fits in any campground we visited. It weighs 5000 lbs. dry. Loaded tongue weight is about 600 to 700 lbs. which is half the Max cargo limit on my F-150. Add adults, dog and camping stuff and our TV is at or slightly over its limit.
Finally, when you think you have the unit. Give yourself a day or so to think it over.
Good luck
