I did a search and found a few recent references to your axle load measurements -- all of which pointed back to:

http://www.airforums.com/forums/show...17&postcount=1

I think that post answered my question about the "50/50 on the tv axles".

I thought you were referring to an equal distribution of tongue weight on the TV axles. And was wondering how you managed to get the TV's share of the tongue weight equally distributed on the TV's axles.

From the 2005 post, it appears you are referring to the total hitched loads on the TV axles -- including both the weight of the TV and the contribution from the TT tongue weight.

The thing that confuses me the most is, The Airstream has 2 axles and so does the tow vehicle. The position of those axles is the only difference. So I think it would make more sense to split it in half rather than per axle because you cant possibly split the trailer axles. On a semi you can only put 12000 lbs on steer, 34000 on each set of tandems (drives and trl) but if you have a single axle drive 20000 is the max on that. So there has to be a ratio on what is OK. Same I would think to be true on a Pickup steering axle that is why the front and rear GVWR is different or even tire pressure is different

mustang

have u checked the axle rating (gawr) on your truck?

cheers

What are you suggesting should be split in half? Is it the TT tongue weight?

By, "split in half", do you mean that one half of the tongue weight should be distributed to the TV axles and one half to the TT axles?

I have 5200 front and 6100 rear GAWR. GVWR is 9200 total It is hard to beleive you can load a front axle the same as a rear, of course the engine weight up front starts it heavier so inturn you transfer less weight to the front and get equal weights. Right?

I'll try to answer by using an example which might or might not correspond to an actual TV/TT combination.

Let's assume the TV, before hitching up the TT, weighs 8000# with the weight distributed 55%/45% on front and rear axles. Also assume the TT has a tongue weight of 1,000#.

The initial TV axle loads would be 4,400# front and 3,600# rear.

After hooking up the TT and before WD is applied, the TV axle loads (depending on TV wheelbase and ball overhang) might change to 3,900# front and 5,100# rear.

If the WD system could remove 720# from the rear axle and add 480# to the front axle, the final TV loads would be 4,380# front and 4,380# rear. At the same time, the WD system must transfer 240# to the TT axles.

The net re-distrubution of load would be:
20# removed from front axle
780# added to rear axle
240# added to TT axles

I called Ford, I asked how much weight can a person load on the steering axle. They told me, it depends on the axle and the springs. A half ton truck unless properly equiped should have no more than 4000 lbs on the steers. He said that is pretty much all mfg. Now telling me this I asked what about my truck 250 super Duty 4x4. I have the snow plow package. HE said that puts beefier springs up front. ( I recall this from another thread in refference to chevy tow vehicle) so they must be simialar. He told me with a snow plow package 6000 lbs is max 250 and 350s Super Duty. My point, Before I load my steering axle, I should check the axles/ spring capactiy, or bad things could happen.

Your truck's driver door jam has a plate that lists the appropriate specs for axle weights along with the tire pressure to get to those weights.

dpandorf I posted those earlier but those are GAWR not GCWR I was always told GCWR is the true carrying capacity I should look at. many people see GVWR and think that is what there trailer weights in at. not true. I dont meen to confuse anyone. GCWR is the easiest for total tow anmount Gross Combine Weight Ratio. then just subtract acctual tow vehicle weight all loaded up by the GCWR and that is how much you can tow.

Agree. A lot to digest and sometimes can be confusing. Like we've talked about here and other forum topics on this site, even though the TV can tow a certain amount is not the whole picture when analyzing the whole picture.

I dont now if this is off topic at this point. I might start another thread. I have called a couple dealers Chevy Toyota and dodge. Everyone I have talked to understands what I am asking but have no DATA to support a answere. It is pretty standard that they have all said no more than 4000 lbs on steering for half ton, BUT I want a definate answere. facts.

WOW !! I have to ask myself, What would Wally do? Did they just hook up and go? Maby they put a ball in the hole on the bumper. Life was less complicated then. Did they even have the W/D hitches?
