My Weights

So I hit the cat scales over the weekend fully loaded and gassed up. Any constructive feedback on my weights or possible wdh adjustments? Tongue weight seems a bit high if I'm calculating correctly at 1620. Thanks in advance!

TV:
Front GAWR - 5200
Rear GAWR - 6100
GVWR - 10,000
Tire Payload - 1877

TV Only Weights:
Steer axle - 5000
Drive axle - 3420
Gross - 8420

TV with WDH Bars:
Steer axle - 4520
Drive axle - 5460
Trailer axle - 8940
Gross - 18,920

TV without WDH Bars:
Steer axle - 4320
Drive axle - 5720
Trailer axle - 8840
Gross - 18,880

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!

Bob

Could you run through the math on how you ended up at 1620lbs? I do not seem to be able to find the correct combination of weights to come up with that number and I have always been pretty good at math.

Sure: (4,320lbs + 5,720lbs) = 10,040lbs...., (10,040lbs - 8,420lbs) = 1,620lbs

Thanks very much for the feedback, Rustic. I agree I could use some more transferred up front. Truck sagged a bit in the back but I didn't think it looked horrible. I'll look into the wdh adjustment. I'm running the equalizer with 14k bars.

DanNJanice - I used the total axle weights of the TV from the third weigh minus the first weigh TV gross weight based on this thread.

Fairly common for a TV to experience a 1" to 2" rear fender sag even after a WDH is dialed-in correctly.

I assume you are referring to the Equal-i-zer brand WDH, which means it's rated at 1,400lb maximum tongue weight. I'm confident it will handle your 1,620lb tongue weight....., but like any WDH when the WDH tongue weight rating is exceeded one "may" experience difficulty transferring/maintaining the exceeded weight to the TV's steering axle. Not all TV/TT combinations react the same with WDH adjustments, so your experience may differ.

If you find it difficult to transfer your target weight to the TV's front axle.., try relocating some of the TT's front cargo thus reducing the loaded tongue weight effect.

I'm confused by the tire payload rating provided. From the sidewall? Of the TV or TT?
In either case, it seems to me that you are exceeding the tire capacity on the steer axle (and drive axle unless duallies), or if that is the trailer capacity, then it is being exceeded there too.

Correct, equalizer brand with the 1400 rated bars. And I did actually pack more stuff in the back on the return trip and things did "feel" a little better, but it could have been in my head too. Looks like I have a few adjustments to make not only to hitch but also how I pack...
