2015 Silverado LTZ RPO Help

[EddieK82]

Hey Everyone,

 

I have had my truck about a year and a half now and did some research on the RPO Codes. Can anyone with more knowledge than me tell me if this truck is good for towing and was worth the 32K I paid for it 1.5 years ago? I posted an image of the glove box rpo codes and looked some of them up, the major ones I looked up are these: 

 

Z82 Trailer Provisions – Special Equipment, H. D. 

Z60 Chassis Package – High Performance,

JL1 Control – Integrated Trailer Brake,

JD9 Brake – VAC Power, 17 inch Disc/Disc, With VSES, 7,700 lbs,

GU6 Axle Rear – 3.42 Ratio. 

KNP trans cooling package

kC4 Heavy Duty Eng oil cooling. Engine: ENGINE GAS, 8 CYL, 5.3L, SIDI VVT, AFM, E85 MAX, ALUM, GM.

 

Are there any other ones I should be interested in that differ from the normal LT? 

 

I'm pretty sure the guy who had it before me was towing something, and something heavy. I had to have the transmission fixed (certified so free) They replaced the pump, valve body and torque converter.

It should tow fine within its capacity. My crew cab has all of that, except Z60. It tows great for what it is.

 

 

Now that I think on it, my 2014 was a double cab Z60 with those same specs. It towed just as well. I never put anything that heavy on it though.

We talked in the other thread, but I didn't have my RPO codes over there. I looked into this some more so wanted to post the codes. I just had the transmission work done, so I'm pretty confident in the new parts. I found a TT that is 7600 Max Capacity and 900lbs hitch weight. I still get people over on the Forest River forum telling me that would be too heavy, but I can't see how it could when it's still giving me 1,500 pounds under the 9,200 i'm rated at, plus the 900lbs hitch weight is way below the 1608 GVWR rate of the truck itself. 

 

A person over there was asking me what my hitch rating was but I can't seams to find that, or have any idea what that really means. Do you have any idea?

You should definitely be fine with that trailer on your truck.

When they say hitch rating, are they referring to your receiver (Z82 is what gets you that, and a plug to the BCM for an aux brake controller if you don't have the integral one)?

It's class IV.

Or are they asking about the ball and mount you put in?

I regularly keep a 2" reese ball with their mount, as what is mostly encountered that can be towed with a 1500 needs a 2" ball. I apologize for my oversight in your other thread, the capacity of the tow bar and ball is also required. The Reese 2" ball and mount only handles 600 tongue weight and 6000 pounds.

If you move up to a 2-5/8" ball and mount, I think that will tolerate a good bit more. I apologize for not knowing, everything I've pulled takes a 2" ball. Uhauls are all 2", which has been the majority of my towing - a dual axle car hauler and the 6x12 enclosed box trailers I've used for moving or hauling old appliances to the landfill.

I'm not sure what he's referring to over there. This is a normal TT so I'm not sure what hitches it needs but they said they'd install the correct balances and whatever where i"m going to buy it. I plan on it being around 7200lbs, I'm not going to load it up with a ton of stuff.

Your truck should tow great, I don't think the transmission was because the guy towed heavy with it. My 2015 truck had the TC changed right away, then a year later it had a delayed and rough reverse engagement and they ended up swapping the trans, I didn't tow over 6,000# before that point either, 8L90e trans was bad on it's debut year which was 2015 for the trucks. 

 

That is a pretty good dollar if you guys are getting $30k for a 2015 LTZ down there. I was going to ask $30k CAD for mine next year at trade time, might try to get it closer to $40k if that's the case. 2015 SLT AT 25,000mi.

I have guys over on the travel trailer forums telling me this is too much weight to be pulled and it's too big.

 

I found another trailer that is less weight and the floor plan I want. I did some numbers and want to run them through here to see what everyone thinks.

https://coachmenrv.com/travel-traile...e/293RLDS/4346

GVWR: 7800#
Hitch Weight: 832#
Full Length: 33'11"

My truck GCWR is 15,000#
Truck GVWR: 7200#
Towing: 9100#

I figure if I don't load the trailer to the max, which I won't, I will be towing roughly 7400#.

So 7400#(trailer) plus 7000(truck hitch, passengers, etc)# = 14400# and I'm under the GCWR by 600#, plus under trailer capacity by 1800# .

Also, I've added in the full tank of fresh water to that equation just for boondockings sake. I probably will not be doing that on a regular basis(if ever), as we plan on going to places with water, at most I'd have a few gallons in there for emergency. So I'd actually be towing roughly 400# less.


Does this sound like I'm pushing it? To me, as a person who knows no better, sounds doable since the truck is rated to tow that and I don't believe Chevy would put the ratings like they do if people had to do math themselves to figure out .80 of weight/capacity and all that.

I'd also like to add that I will not be towing into the mountains, ever. I will be sticking to I95 from Philly to Florida and maybe the Gulf coast of Florida to Texas/Cali.

My towing habits will be to drive to a destination, stay a few weeks and then tow to the next, maybe no more than 200 or 300 miles for another 2 weeks. This will not be an all year thing, just a month, month and a half at a time, then home for a few months where the TT will sit in my backyard and be my mancave.

 

Can I please have your thoughts on this? I'm trying to get chevy truck guys input, as well as input from people who pull TT's.

If the hitch weight is 840# your truck wont struggle with it much as long as you don't fill your truck with gear. Bumper pull trailer I would assume. You can keep all your camping supplies in the rear of the trailer to help a bit.  Your curb weight is around 5500-6000# so you have nearly 2000-2500# of payload cap available. 1000 for your trailer, 400 for you the wife dog and some tools, still have 1000 to go but you will leave some weight on the truck's front axle with a bumper pull. You might come close to maxing the rear axle though so I would look into a weight distribution hitch, maybe some helper bags. Overall you wont hit your total GVWR, you just might be close on your GAWR on the rear but you will still have some room. Anything under the manufactures ratings will feel fine and tow really well. You will be good to go with that trailer. The 8 speed tows great.
