Owners manual has 5.3/3.73 max trailer at 7700lbs, But it shows 5.3/3.42/tow-haul-pkg at 9500lbs. mine is 5.3/3.73/tow-haul-pkg. My understanding is the 3.73 should give me more than the 3.42, but there doesn't seem to be any data to back that up. So i just been assuming i have as much as the 3.42/tow-haul-pkg.
Heartbeat: 4spd with tow/haul, more info in my sig.

GAWR (both front and back) is 3,950lb
When I bought the truck (out of state) I had to weigh it to get it registered and it was 5,440lb (can't remember if I was sitting in it or not at the time), but I'm guessing this puts the rear axle weight at around 2,700lb and this would give me about 1,200lbs for the trailer hitch and additional cargo in bed to reach my axle limit so I think I should be ok there. Here are my assumptions:
450 me, wife & 2 kids
5,536 trailer dry
2,000 cargo in truck bed/trailer (don't think actual cargo will be this much)
With the above assumptions I am still under the 15,000 GCWR and I think I'm ok with the rear axle limit and truck wont be over the 7,000 GVWR and total trailer weight is not at 9,500 either. Anyone please speak up if I am missing something...

Heartbeat, read your links at work today, good stuff but I got a question for you. You say your temp would get 180/190 and sometimes over 200 when towing your boat so I paid attention to my temp guage on my way home tonight and it was right at 210 the entire time, didnt budge. This got me a little nervous so I pulled out my manual and it said that the temp should be at 210 or below (which made me feel better) and I should be concerned if it gets up over 260 when towing, this got me wondering why I am at the levels with normal driving that you are when towing. Think there is any reason for concern for normal driving to be at 210?
Tony....before installing the Aftermarket Trans. Cooler, my Trans.Temps were between 140/150 when driving down highway, not towing.....and when towing my temps as I mentioned above between 180 to at times 200.....in the 99" Owners Manual......it expressed that it is Normal for Trans. Temps to have a Operating Range from 100 to about 265.....
So my Trans. Temps were with-in the range mentioned above, but I was Not Comfortable having my Trans. running at those Temps....so next to installing the Aftermarket Cooler, I've done 2 other Mods/Upgrades to my Transmission.....the 1st was going with Synthetic Transmission Fluid and the 2nd was replacing the Factory Steel Transmission Pan, with a Aluminum Finned Deep Transmission pan, from Mag-Hytec(Link Below).......next to the Aluminum finned also being a deep pan it holds...3-1/3 quarts more than the Factory pan......my Trans Temps dropped to 10 degrees.....to around 180/190......and now with the New Larger Trans. Cooler my Temps have Not gone over 150-Degrees!!.....when towing my Boat......take a look at the Mag-Hytec link below....it has a Chart that shows Transmission Life Relative to Fluid Temperature.
For me installing these aftermarket parts have help with reducing my Transmission Temps......when towing and for me it is peace of mind.

Have one more rookie question thats confusing to me, when I see a trailer's dry weight (or shipping weight) listed at 5,536 and the hitch weight at 589 (in this example), I was adding these together in my calculation and treating the trailer as being 6,125. Im now starting to question this, does the 5,536 figure already include the hitch weight and perhaps the only reason for listing it separately is to show staying within 10%-15% of trailer weight and for rear axle weight calculation?
Also, if i am going to be using a weight distribution hitch, do I still need to include the hitch weight in my rear axle calculation or maybe just 50% of it since it will now be spread across both axles?
Thanks again, you guys have been a great help and I really appreciate it.

Tony.....that's not a rookie question that's a Very good question.....I would say that the weight of 6125lbs, as you are adding both of these 2 weights to the load your going to be Towing......
Below is a Link, that talks about WD and Hitch Weight, this may have the correct answers to your Questions,

Tony.....the following information is from the 2011" Siverado Owners Manual....The Trailer Tongue Weight (A) should be 10 percent to 15 percent of the.....(Total Loaded Trailer Weight).....up to a Maximum of 600 lbs (272 kg) for the 1500 or 2500 series....
And up to a maximum of 750 lbs (340 kg) for the 2500 HD or 3500 series with a weight carrying hitch. The trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight, up to a maximum of 1,000 lbs (453 kg) for the 1500 series and up to a maximum of 1,500 lbs (680 kg) for the 2500, 2500 HD or 3500 series with a ......(Weight Distributing Hitch).......
Tony, the way I'm reading the above information......is to get the 10% percent to 15% percent is based off of the .....(Total Loaded Trailer Weight) with a Weight Distributing Hitch.......where does the.....586lbs from Hitch fit in here??.....I'm sorry I don't use a WD Hitch for Towing my Boat.....hopefully one or more of the members who use a WD Hitch will give some insight.
My question is where does the Weight of the WD Hitch fit In???

When travel trailers list their total weight, that's the total actual weight of the trailer. The tounge weight usually is around 10% of the total trailer weight. For example, my camper weighs 9000 pounds minus cargo and has a tounge weight of 900 pounds. They way you distribute your cargo in the trailer affects the tounge weight, and of course adds to the total trailer weight.Christopher
