Kim,

First of all, welcome to the RV Dreams forums.  You will find this to be a good source of information for just about any kind of RV and any kind of aspect of the full time living of the RV lifestyle.  There are folks here that are very knowledgeable, friendly, helpful, and downright encouraging, so you sound like you'll fit right into the "family."

With regards to an RV for full-timing, I always suggest that one look at the very foundation of the RV's, and that would be the frame, suspension, axles, wheels and tires.  Since those are the foundation of the "new home," be sure that they are of good quality.  This is not the place to scrimp, unless one is going to park them and hardly move them.

While looking at the different models at showrooms and RV shows, go in with an idea of what you insist on having, what would be nice to have, and what would not be suitable at all.  Spend some time in each with an eye towards "how would this work for ......"  That would be like looking at the kitchen with storage, and working space in consideration, stand in the shower and see if it is "inconvenient" by being too narrow or too short.

Fifth wheels have their hallways on both sides and in the middle, so consider whether it is important to you to be able to access the bedroom and bathroom, even with the slides pulled in during travel.  Some folks insist on that and others don't.  We have a side bathroom and it is inaccessible when towing unless we stop and put out slides.  However, we figure we spend more time "living" in ours and less time "traveling," so we are fine with facilities in rest areas and truck stops.

With some models, if one gets a queen bed instead of a king, one might find that both sides have a "nightstand" for glasses, books, and the dreaded alarm clock.  We have a DRV Suites Mobile Suites and it has the queen-sized Select Comfort bed, so we have two nightstands with storage within.  (Go to my Photobucket account link in my signature and look for "Our New Home" for pictures of what I am describing.)

If you think you will always be somewhere that 50 amp electric is available, look at the possibility of getting something with a residential refrigerator.  Ours came with a regular RV style fridge but it started giving us trouble after less than two years of living in it.  So, we modified ours and put in a Samsung refrigerator with two doors and a freezer drawer below.

Your truck is a good one for "almost" any of the different fifth wheels.  The DRV Suites models like ours are some of the heaviest, but a number of those owners have the same truck you do.

Good luck with your research and planning, and feel free to ask any questions that come to mind.  We all tend to learn from each other, so every questioner brings the potential of a different perspective to old topics.
