trailer weights 9990 or 10000

Ah we go over 150 air miles and we go out of state.

I don't want to go up. When I make a move it will be down to the under 26k GCWR territory.

Since you're commercial, you'd need a med card, fire ex., DOT number and probably a log book.

Amazing you haven't been nailed yet. Your buddies nickname you "lucky" yet?

Yes I am lucky. They DOT enforcement truck did stop me once but luckily I was just pulling the empty trailer. Told em I was going to haul a load of hay, which I often do, just not that day, they waved me on. One day they are going to hit me and hit me hard though. I have been pulling this trailer since 03' and have run in Missouri, Illinois, Iowa, Kansas, Nebraska, Oklahoma, Texas, Arkansas, and Kentucky, and have never been stopped. I bet I got almost 200,000 miles on this trailer under various trucks. Ya I guess I am lucky, or maybe just dumb.

BTW: Love the 7040.
Any regrets?
I really need a cab/utility/4x4 ~60HP

Nope I love it. My only regret is my checkbook is $30,000 lighter! But I was really sick and tired of coughing up brown crap for a week after spending a day in the hayfield.

I don't know, I guess I just get sick and tired of every guy pulling a BX2200 behind and F150 come on here and ask if he needs a CDL?

And I'm supposed to take this how?

Don't take it the wrong way. I think what he's trying to say is there seems to be a rash of topics about needing/not needing a CDL.

As with many other repetitive questions, guys just need to learn to not get frustrated.

On CDL questions, guys need to consult their states DMV regulations to get the correct answer, rather than ask someone's opinion on a website.

Axle ratio directly affects the GCWR, at least with Dodge. A truck with a 4.10 axle ratio in many cases has a higher GCWR than a truck with a 3.73 axle ratio.

You are basically correct about axle ratio affecting GCWR. On Ford F250/350's when you go up one ratio it adds like 2000 lbs to the tow capacity in their specs. I believe GM is similar.
What I don't understand is how any of this affects safety. If two identical trucks are equipped exactly the same except one has a 3.73 and the other a 4.1 does that make the one with the 3.73 less safe than the one with the 4.1? It might be a dog on acceleration or put undo strain on the engine/transmission but it shouldn't be any less safe going down the road as far as handling and braking.
With the 3.73 a truck might be rated by the manufacturer to tow 15,000#, and with the 4.1 it would be 17,000# with the same engine and transmission.
If what Builder says is true and enforcement people can actually check in a data base by VIN, then the guy with the 4.1 would be legal towing 16K while the person trying the same with a 3.73 would be illegal and subject to enforcement action. Does this make any sense when in all other respects the trucks are the same (brakes, suspension, axle ratings, etc)?

Thats kool by me.Its just that technically I didnt ask a CDL question.I just found it curious as to why people are buyying 9990 trailers when theres 10000# trailers and the "magic" number is 10001.The reason I asked in the first place is because I've got a 10000# trailer that i've been using for 6 months and the owner asked me if I'd be interested in buying it.Obviously if theres some advantage to a 9990 trailer I'll decline and just buy a 9990 deckover instead.This one has fenders. i'm a developer/builder and I like the side access aforded on a deckover.

One could propose that "a dog on acceleration" IS less safe. Think of merging on freeways, etc.

I think they're rated for more because the launch of a 4.10 rear puts less strain on the transmission and the bottom end of the engine. The manufacturer might not be able to warrant an engine if it is lugged down too low. The 4.10 rating might also keep the engine up more in the RPM range and therefore provide better engine braking.

Truth is, I'm hypothesizing. I wasn't in the room when the engineers came up with the reasons for their ratings.

However, I do know it has nothing to do with the "strength" of a 3.73 Dana 80 versus a 4.10 Dana 80. They're the same in terms of supporting weight.

The different tow ratings are more because the truck performs differently in front of a 3.73 vesus a 4.10.

That's my theory and I'm stickin to it.
