" I really want to hear from the current 5th wheel owners on how you would approach this."
It's really easy. Take the RV's GVWR and take 25% of that weight so let's say 16K potential RV now that would make a potential 4K pin. So take the rear axle weight of let's say a RAM 3500 SRW with two passengers, hitch and tool box plus hitch at 3,600# or so. Is there still 4K of capacity between that # and the trucks RAWR?
Now on my Dually it weighed almost 4K on rear axle ready to tow so using my math my RV's GVWR was 21K so 25% of that is 5,250. Add that to 4k it's 5,250# 700# below my RAWR. BUT it's a good thing I allowed extra capacity because my RV weighs 23K with 25% pin and it puts me right at my trucks RAWR.
I was a bit over RAWR from carrying a complete SouthBend clutch, pressure plate and flywheel assembly.
