I saw a build thread.
Guy in Alaska, took a ram 5500.
Made it a srw with 16 ply tires.
Kept the same gvwr. It was crazy.
Put a srw bed on it too.
Full air ride.

You'll find conflicting opinions on this. I've been RVing since the mid 70s, pulled and driven most all of the different types, from slide-in campers to class "A's". Currently have a class "C" MH and a 33' 5th wheel. I got out of two 1 ton DRW to get a 3/4 SRW so I could park where I wanted, and go thru the car wash. My rule is don't exceed the GCWR of the truck (truck + trailer) and don't exceed the rear axle rating, in my case 6000#. I don't worry the GVWR unless what I'm pulling, or hauling, is something that doesn't have it's own brakes (read slide-in camper). Too many people trading away perfectly capable trucks to achieve a payload capacity that's not necessary. Two parameters with trailers: GCWR and RAWR!!

Question regarding 5th wheel pin weight

Why is it, the only ones disputing gvwr, are the ones that are running over gross in 3/4T??

Gvwr is the most important.

Why adhere to combined, and rear axle... But toss out gvwr?

Side note...Why don't they make a dually where the axle is narrower and all four tires fit in the standard width bed? I realize the space between the wheelhouses would be reduced, but I am pretty sure there would still be plenty of room for a 5th wheel hitch. I would consider this option long before buying one the way they build them now.
X 2!

Best way to get the true Payload is to go to a CAT scale and weigh the truck with all your stuff in it. Look at the door jam GVWR (my 2500 is 10,000). Subtract your CAT score from the GVWR and that's your remaining Payload for the trailer.

Now when shopping for the 5er, remember the mfg published pin weight doesn't include the 60# battery and the dual 45# propane tanks.

Some experienced towers compare their payload numbers to whats available for the truck's published rear axle and tires. For instance, my truck's GVWR is 10,000 but the GWR for the front axle plus the rear axle is 11,200. My rig fully loaded is about 1,000 below the Rear rating but almost exactly on the GVWR rating.
Pretty sure Forest River's published dry weights include full propane tanks.

Heck Kenny a lot of people throw out GVWR, GAWR, GCWR and just go by what the website says they can tow. IE F150 can tow 11,500lbs

Many folks think that as long as they are under their axle ratings they are "good to go".

In reality if you add the front and rear axle ratings together, you will find the total is more than the Gross Vehicle Weight Rating of the truck. The reason for this is the frame of the truck is the limiting factor in every case (I have found anyway). Yes, it is possible to be under your individual axle ratings, yet still be overloaded.

It was explained to me that the difference in total axle weights and the GVWR is because the Axle Ratings are based off static weight. During towing static weight can increase by 30% or more - like you are going down a hill and put the brakes on the weight from the RV will shift forward on to the pin. The guy that was explaining this was a worked for Ford in the engineering department and now retired and teaching at college engineering classes part time.
