You've been given some pretty good name brands to consider and you'll probably get more, but as one poster stated, if you go with the higher end, better insulated, more "home like" 5er, it WILL equate to "heavy"....Do yourself a favor and when looking at the 5er you think you might purchase, look at the units GVW, NOT it's empty or dry weight and empty or dry pin weight....no sense in messing with that unless you won't be putting anything into the 5er:).
Having stated what you're looking at and possibly hoping that a 1 ton dually will handle it, "might" limit you as to what you'll purchase as far as 5th wheels go....
It's possible that a 1 ton dually will handle what you want to get, just saying use a little common sense and do the math when you match up your combo to help you have a more enjoyable towing experience.
There are 1 ton dually's out there that can now handle quite a bit of weight and very well may be all you need once you pick out the 5er you want. Any of the Big Three very well may be able to "foot the bill" if looking at the newer ones. My truck has a GVWR of 14,000# with a 9750# rear axle weight rating, so it could take a lot of pin weight and with a GCWR (gross combined weight), of 37,500# (with 4:10 rear end), could handle some fairly heavy 5er's...just remember, the higher the quality, probably the heavier the 5er, which also can equate into much higher pin weight.
Again, you had several very high end models recommended and I guess it'll depend more on your budget. I understand Artic Fox offers a very good 4 seasons 5er and Carriage also has some very good units.
Good luck in your search, hope you find the 5er and TV that'll work best for your needs.
