I would go back to your RV dealer and advise them that they provided you with an "underrated" WDH for the 26RKS...., and that with the Jayco designed loaded weight potential of the 26RKS the 800b rated WDH could easily create a TV handling and safety issue. Plus, you advised them at the get-go you felt a 1,000lb rated WDH would be more appropriate based on your calculated loaded TT weights. With most standard WDH brands this would only require the "dealer" swapping out the spring bars.
As mentioned the 2015 26RKS has a 8,400lb GVWR. The published UVW is 5,605lbs, but the actual "shipped" UVW is heavier (actual shipped UVW is noted on TT yellow sticker).
The 26RKS is a 29ft long TT, so a loaded tongue weight in the 13% to 15% range (of loaded gross weight) would be recommended for adequate TV handling.
Scenario #1 (worst case): TT loaded to GVWR of 8,400lbs = 1,092lbs to 1,260lbs loaded tongue weight.
Scenario #2 (moderate case): (5,605 UVW) + (400lbs for ship weight delta) + (100lbs Dealer added battery, etc.) + (700lbs cargo, no fluids
) = 6,805lbs Loaded TT
A 6,805lb loaded TT = 884lb to 1,020lb recommended loaded tongue weight range. An 800lb rated WDH is not sufficient.
Incorporating your actual 26RKS's shipped UVW, add weight for fluids if applicable, if your loading habits are on the heavy side adjust accordingly..., for a more accurate representation.
If you dealer disagrees with the above examples then IMO they are not looking out for your best interest.
Hope this helps.
