FYI, I have a 2015 Vista 27N (it's like the 2016, etc. 27N LX and early versions of the Adventurer 27Ns before they upgraded the Adventurer 27N to two ACs and 50 Amps), it's length is 29' 6" with 3 slides including a long slide on the passenger side and it's OCCC label says 2767 lbs. I had mine 4 corners weighted at Escapees in Livingston and can confirm this is accurate. It carries slightly under 1,000 pounds more weight on the passenger side tires than on the driver's side tires when loaded for normal use - because kitchen/dining item storage, refrigerator, pantry, 9 drawer dresser, and most of the basement storage is on the passenger side. This has never caused me any issues , but according to my TPMS the passenger side tires run a few PSI higher when warmed up during travel due to the higher loading.
With full water and full cargo Escapees Smart Weigh calculated I was about 800 pounds under on OCCC for my particular coach including my weight as the driver.
FYI, I'm not too surprised that the OCCC has dropped from 2700 to 2200 over the years, as they now have 5,500 W Onan vs. the former 4,000 W one, two ACs vs. one, they now have 50 Amp vs 30 Amp Electrical, Front power shade, Studio Loft front bed, and some styling changes like tile in bath and kitchen that added weight.
