Eye opening CAT weighing

For last weekend's camping, I was going by a truck stop with CAT scales and wanted to get some ready to camp weights on my rig. Onboard was my wife, lab, & me.
I had to get out to use the call buttons, likely causing a little of the noticed errors, like the reweighing being 160# less, even though I tried to at least straddle the 1st & 2nd scale platforms. For the reweigh, I just took off the load bars and put them in the TV.
My TV GVWR IS 6180, with WDH the TV axles totaled 5920, without WDH 5840.
Front axle rated at 2960, with WDH 2600, without 2380.
Rear axle rated at 3340, with WDH 3320, without 3460!
Trailer axle weighed in with WDH 3680, without WDH 3600.
First Gross weight was 9600, reweigh was 9440?
So yes, the numbers do NOT all match up mathematically.
I did not unhook for a tongue weight nor did I get a just the TV weight. Two missing parts of the puzzle. The TV is rated to tow 5225 with the factory tow package, so I have got a good safety margin there, although I only have 260# margin on my GVWR when using the WDH.

What I do surmise, I am slightly over weight on my rear axle until I put the load bars on. I need to put anything I can from the TV into the trailer and clear out whatever gear I can out of the TV. The WDH is putting 220# to the front axle.
Other than get a new TV (not an option this year), any comments or suggestions? Should I increase the leverage on the load bars to move more weight to the front? It's a flat bar and platform linkage, so not as simple as bumping up a chain link. Husky Centerline with 600/6K load bars. Right now I feel really stable and level when towing.

    YES....re-adjust WDH to move MORE weight to TV Front axle

    Then go camping!


    Read, he already added weight to the front.

    Sounds like it's setup just right. oP, don't get hung up on a couple hundred lbs when talking capacities. That is a very small margin of error on things with factors of safety.
    If it actually worries you, get something bigger than needed for your towing duties.

    Just crawled under the TT to check the axle. Clearly marked 3500 pounds. So all the extra/overage listed in the specs is tongue weight. And, if I understand how the WDH works, more tension puts not only more weight to the TV's front axle but some goes back to the TT axle. Man, I really need to diagram out my rig with weights so I can clearly explain to SWMBO our limitations in TT loading.
    Still unloading stuff. Cut our metal silverware weight by half, saved another 1.05#! That was in addition to removing 26.4# from the TT last night, and 23# from the TV. Discussed leaving the cast iron at home depending on our menu, that went over surprisingly well ;)
    Haven't used the factory metal platform yet, considering moving the spare tire elsewhere and pulling the platform. It's got to be 40-50#.


    You just said it towa well. HP is one thing you recognize it's lacking. Handling is acceptable, so don't drove yourself nuts storing silverware in the glove box and splitting the tools to 4 corners of the TT.
    You're good!

    Thanks. I was just shocked at that I was well past the capacities of the TT & TV axles.
    I will keep it in mind for each future loadout until I get a higher capacity TV.
    I'll keep nickel & dimeing the items in the trailer and my TV to cut more weight but I won't obsess (too much more) on it ;)
  • When running at max trailer axle weight or more, the tires are the biggest concern. Stepping up a size or even a diameter (new rims of course) would help immensely (provided you have the wheel well room for the larger tires). You will find that the tires are probably the exact same weight capacity as the axle. If nothing else, get a set of the best tires you can find for a trailer. I'm going to suggest Carlisle Radial Trail HD on the success of a co-worker with that tire, and I haven't read of problems with it. I think Goodyear also has a decent trailer tire.

  • Double checked my tires. While they are Castle Rock, they are load range D, 8 PR equivalent, rated for 75 mph, and 2040#. So they mate well with a 3500# axle and should be able to handle the extra weight. I have not yet found a 205/75R14 in a load range E. Bigger wheels & tires, IMO, really should have the axle replaced with a 5K and that isn't cost effective.
