Your math is correct, 1,620lb loaded tongue weight based on your present loaded TT conditions at the CAT. Your TT loaded gross weight is 10,460lbs so your ideal loaded tongue weight would be 1,360lbs to 1,569lbs (13% to 15%)......., so your 1,620lbs is close to ideal for your loaded 338RETS. The 2016 338RETS GVWR is 10,950lbs.
Your TV loaded gross weight (WDH engaged) is 9,980lbs (TV GVWR is 10,000lbs).
TV steer axle: (5,000lb - 4,320lb) = 680lbs removed..., (4,520lb - 4,320lb) = 200lbs actually returned. You still need to transfer some more weight to your TV's steer axle..., IMO at least another 300lbs.
NOTE: Returning as close to 100% of the weight removed from the steer axle IMO is ideal......, but some manufactures give some allowance on the 100% figure, but, they state it in terms of "returned front suspension height
" (25% height, 50% height, etc.), check your owners manual. I found with my 2500HD TV
that 50% front suspension height return doesn't equal 50% weight return...... it was less.
What is the weight rating of your WDH?
Also, if your TV has the OEM 2 1/2" receiver pin box, please note that using a 2" pin box insert to accommodate a 2" draw bar reduces the TV's OEM receiver's stamped WDH weight rating capacity.
Just food for thought......., and please double check my math!
