"ultimate towing thread
This is a trhead I try to build to bring together as more info as possible concerning towing with our Nissan Frontier.
OEM technical:
V6 4L frontier can tow up to 6500lbs, depending of version. in order to respect oem specs, 3500lbs is max tow without trailer brake (some places it's 1000 and other 1500 in owner manual), 5000lbs with trailer brake/without weight distribution hitch. To reach max towing capacity, we should use weight distribution hitch.
According to OEM specs, we shouldn't put over 500lbs tongue weight without weight distribution hitch.
following numbers are based on 2013 frontier Ebrochure. Specs are the same for all 2nd gen. Frontier from what I know.
V6 KingCab 4x2 (4x4) towing: 6500(6300)
V6 CrewCab 4x2 4X4) towing: 6300(6100)
4L kingCab towing: 3500
Payload vary alot depending of engine (4L or V6), cab (kingcab or crewcab), wheelbase and transmission.
To get real numbers, you should refer to your driver door sticker. You'll find there GVWR (gross vehicule weight rating) GAWR (gross axle weight rating) for both front and rear axle.
In the owner manual, we can find GCWR (gross combinated weight rating). That report to max total weight from truck and trailer together. From my owner manual (2011 ):
KC 4x2 4cyl: 7940lbs
All 6cyl: 11135lbs
That mean:
- when loading our trucks, we should never exceed GAWR of both axle.
- Total of both axle weight should never exceed GVWR.
- When hooking up a trailer, we put weight on truck, so load and people on the truck AND tongue weight have to be consider together.
- All weight on the truck reduce max trailer weight we should hook up to our truck
- Only owner, fuel, all fluids and oem options take place on "dry vehicule weight" (read without load). All other person/load/equipment add weight, so reduce usable payload.
Some concept: Tongue weight should be between 10-15% of trailer weight. more than 15% could get you into a "high nose" situation on the road, ie less handling and braking, and more possibility to wobble. less than 10% can bring you on a "nose heavy" situation. Here, weight tend to be more on the read part of trailer, and could bring a dangerous situation, where there is almost no weight on front axle. That mean poor handling, and no possibility to controle the truck. Both situations must be avoid. If there is too much weight on tongue, we should replace load on trailer.
Use of Airbags, helper springs, AAL or any other mecanical way to raise rearend of the truck only mask trouble. Yeah, truck is leveled, but there is still too much weight on rear axle (mecanical stress) and not enough on front axle (poor andling and driving, and braking). We should use weight distribution hitch to level truck. That system help transfering weight form rear to front axle. All other mechanical device only reduce bottoming.
Our trucks are pre-wired for trailer harness. For the 4 wire system, plug is located under left frame rail. For 7pin harness, we have to install a relay harness on front passenger kick panel. Ask dealer for that. (will try to add info-pics later). Realy easy to install. There is also a brake wiring harness under dash. Realy easy to hook up brake controller.
All class 3-4 hitch are almost the same four our truck. Some are rated 5000/6000lbs, some other are rated 5000/8000lbs. They are realy easy to install. / bolts each side. Be sure to torque well, and check after few miles towing.
Use of a good brake controller is a must. I use a Tekonsha P3. Prodigy/prodigy2 are excellent brake controlers. I recommend Inertia basez auto-leveling system. Time based always give you same braking power on a preset patern. In case of emergency braking, they won't give you all power unless you override. Same for smooth braking, or changing surface and backing. Inertia non self-leveling are also hard to fine tune and should be retune for every load and road surface.
Frontier have a great frame, nice powerfull engine, a solid transmission. Taking care of them will help any time. If towing significantly, change all diff3transfer case fluid every year. Can be done easily on driveway at home. Some good "hwo-to" over site. How To: Front + Rear Differential && Transfercase Fluid Change on 05+ Gen 2 Frontier
Tranny fluid should be change every 2 years (flush/fill). Checking tire pressure, all fluids and hitch integrity before each start when towint is one of the best safety/care trick.
When towing, if you encounter any repeating gear change, remove over drive (OD). We do not have a "Tow/haul" mode on our truck. Also, if towing heavy load and tranny is reving very low, you can manualy change gear to a lower one if you have an Auto trans. Our bigger ennemy is by far wind drag. So speed effect towing alot. All vertical surface increase drag... going upwind is realy harder than downwind. Also, crosswind/crossing heavy trucks can be a little tricky if not knowing what will happen, or not familliar in towing a trailer.
See local laws regarding towing. Vary from state to state, and from a province to another. Lighting, lenght, weight, license plate, mechanical inspection...
Remember that heavier weight takes longer to stop, so keep place in front of you, and slow down a bit...
For those who want to know if they can tow something, don't thrust trailer dealer (rv especially!!) and truck dealer too. They want to sell, and they are not in your truck down hill, without electrical brake, overloaded... but they have your $$$. I would suggest to refer to RV forums. You can find alot or tricks, info, and sometime the exact setup you wanna try or ask questions about. But remember: the longuer anr/or heavier the truck, the larger the trailer it can handle. The longuer the trailer is, there is a greater lateral swing force that can be transfer to the truck." End of quote
