We have a '18 3560SS, slide toppers, 5th Airborne hitch, full propane and right after p/u from dealer (new) went to CAT scale and it weighed in at 14,000 even. Couple months later, loved up for week vaykay, 3 people, now weighed 15,980. Started off w/ a SRW '15 F350, 4x4, cc, sb and was overweight on everything with the tires being my major concern. in 2018. Truck toed it fine, but did add Too Lift Stable Loads to the springs and that aided in reducing the rear spring drop. Truck tho was a tad wiggley and wife felt a tad uneasy when she relieved me at times so I could catch a couple Z's. Compared to the old coach which was much lighter. In 2018, decided that FL in Aug vaykay was decided and knowing the tires were already the weakest link, hated to do it, but swapped the ;15 SRW in for a '17 F350 DRW,4x4,cc and while it stinks in the snow, it is AWESOME for towing this coach. Wife feels much more comfy towing w/ this try and she doesn't tow very much.
Sticker on door jam of the coach says it's under 14K, but CAT scale says otherwise and I trust the scale. FWIW, w/ the dually, fully loaded for a week, 3 people, 35lb dog and cat now weigh just under 25,000. Hope this helps.
Oops, while I went on and on, didn't answer the OP question directly. Empty pin is around 2800 and fully loaded is 3700. Going off memory cuz I cannot find my notebook w/ the weights I wrote down when I weighed it.
