Happy camper here Crabman.

This forum saved my arse again big time today.

A couple small changes and I should be good to go.

Now off to pull the WDH washers.

Best regards,
Doug

Doug,
Once you have changed the washer count, check the front bumper height with WD and then with the TV alone. My guess is the front bumper should be between 1/8 to 1/4 inch higher when hitched up to give you the FAW you're looking for.

Thanks Dave,
I pulled 2 washers.
Getting dark here, so I'll check it tomorrow.
I'll shoot for 1/8"-1/4" higher on the front.

Once I think it's right, I'll take it back to the scales if it's not a total washout here.
Suppose to have severe thunderstorms tomorrow and then clear sailing to Amarillo through next week.

Best regards,
Doug

Doug,

Great CAT scale data!

Looks like Lee and Dave steered you in the right direction with accurate feedback, and I will add a little to the disscussion...., so please advise me if I misinterpret your data.

TV Front Suspension: (TV/TT hitched/WD engaged TV Front Axle = 2,580lbs) - (TV only loaded Front Axle = 2,480lbs) = 100lbs to much weight transferred to front axle. Your target TV front axle "return" weight is the unhitched weight of 2,480lbs, not the front GAWR of 2,550lbs.

TV GVWR: (TV GVWR 5,580lbs) - (2,580lbs + 2,680lbs) = 320lbs remaining (something to watch if your TV wasn't fully loaded).

It should be noted that some of your prior CAT weights may change a little once you re-adjust the WDH to the correct weight (2,480lbs) to the TV's front axle with the WDH engaged.

Please confirm my math, I'm racing against a poor WIFI connection

Bob

Hi Bob,
Thanks for taking a look at my data. I was hoping to hear from you.
You are correct. My set up today was +100lbs versus unhitched on the front axle.

Luckily, my tow vehicle was fully loaded, full gas etc. So hopefully I have a small cushion there for a couple jackets or whatever.

I hope to get back to the CAT scales tomorrow to make sure I've reduced that 100lbs back to something equal to or slightly less than unhitched front axle weight.

I've loss my touch being retired for 14 months now. I used to be a little better crunching data lol. Thanks much my friend.

Kind regards,
Doug

Doug,

I know what you mean about the effect of retirement on crunching numbers, I'm in the same boat!

Oh, take a copy of the JOF CAT scale sticky with you, I formatted it to a TV/TT combination.

2ND VISIT TO CAT SCALE AFTER ADJUSTMENTS
Adjustments made:
1. Moved about 30 lbs of cargo from front to rear of TT
2. Removed 2 washers from Hitch Tilt (tilted ball towards TV more)
3. Raised hitch ball 1 hole (~1.0")
4. Raised spring bar brackets up 1 hole (~1")
5. Added fuel. I thought I was at least 3/4 full yesterday, but actually was at 1/4 full. I burnt up about 1/2 tank testing and finding CAT Scale :-)

Summary Results:
1. Tongue weight = 540 (previously at 580)
2. Front axle weight = 2460 98.4% (previously 104%)
3. TT front 1/2" lower than rear (previously 1")
4. More clearance between ground and spring bar brackets
5. TV front ground to wheel well 35.5" (previously 35.25") (up .25" versus unhitched)
6. TV rear ground to wheel well 36" (previously 36.5") (down 1" versus unhitched)
7. Front axel within rating returned to 98.4% of unhitched
8. Rear axle within rating
9. TT within rating 3,340 (rated at 3,500)
10. Noticeable improvement in handling. About 10% better

TV GAWR Front = 2,550 (Tow vehicle Gross Axle Weight Rating Front)
TV GAWR Rear = 3,060 (Tow vehicle Gross Axle Weight Rating Rear)
TV GVWR = 5,580 (Tow vehicle Gross Vehicle Weight Rating)
TV GCWR = 10,580 (Tow vehicle Gross Combined Vehicle Weight Rating)

Hitch GTWR = 5,000 (Hitch Tow Weight Rating)
Hitch TWR = 600 (Hitch Tongue Weight Rating)

TT GVWR = 3,500 (Trailer Gross Vehicle Weight Rating)

2ND CAT SCALE RESULTS
Weight #1 = (Weight of the TV and attached towable with the WDH activated)
TV Steer Axle = 2,460
TV Drive Axle = 2,2940
Towable Axle = 2,960
Note 1: WDH returned front axle to 98.4% of unhitched
Note 2: WDH reduced weight on TV rear axle by 400lbs

Weight #2 = (Weight of the TV and attached towable with WDH deactivated, but attached)
TV Steer Axle = 2,200
TV Drive Axle = 3,340 (added ~100lbs of fuel today)
Towable Axle = 2,800


Weight #3: = Weight of loaded TV (unhitched from towable)
TV Steer Axle = 2,500
TV Drive Axle = 2,500
Note 1: Tongue weight = (2,200+3,340) - (2,500 +2,500) = 540 lbs

I think this is my final set-up.
I could raise spring bars 1", but not sure I want to chance exceeding 100% on front axle.

Best regards,
Doug

All that fine tuning and confirming weights should sure make you feel confident as you start on you trip out West. Good work, and thanks for sharing the details.

Very true Clubhouse. Worth every penny.
Especially with this tow vehicle, it's not the best when set up correctly.
At least I know I am safe and handling is as good as it can be.

Highly recommend doing the CAT scale, even if it's an academic exercise. Nice having the numbers and not guessing.
The site I went to was $10 1st weigh, $2 each additional weigh.

Best regards,
Doug
