First of all please let me apologize for being less educated in this area. We are looking to purchase our first travel trailer(Jayflight 29BHDB).
I just purchased a leftover 2016 Lariat 502A 4x4 supercrew.
5.0
3.31 gearing
trailer towing package,brake controler,cooler,etc
GVWR 7000
GAWR front 3525/ rear 3800

GVWR 2017 Jayco 6930 dry

I'm thinking I might be to close to my max weight and need to seek a smaller floor plan. Suggestions please?

Also the selling dealer is pushing the Blue ox hitch system for towing. Any thoughts or recommendations?

Thank you in advance

Martiangod

the blue ox is one of the best.
Loaded your going to be over 8000lb most likely.
The truck will pull it.
do you know what the tounge weight is on the trailerÉ
i.m pulling over 8000 5th wheel with my 15 5 liter 3.31 gears.
just revs like a race car going up hills in second gear....love that sound

You left out the MOST important spec of your truck, the payload! That is the #1 determination of what you can tow, regardless of what packages may have been installed.

Payload determines how much weight you can tow/haul, and nothing else will.

Being a 502a, but not knowing what other options are installed, guessing the payload is 1600 or less. This limits the truck to roughly a 7100-7500# GVWR trailer porvided you pack the truck lightly.

Example of the 7100-7500GVWR Fully loaded, the trailer at 10% tongue will be 710-750#, so you are at 850# with the hitch, leaving you with 750# for passengers and other gear.

The more tongue weight %, the less cargo and passengers you can carry.

BTW the dealer will push whichever hitch makes them the most money. It is a good hitch from what I read, but so are the others. The most important part of the hitch though, make damn sure whoever installs and sets it up knows what they are doing.

Thanks for the reply!! According to Ford's towing chart I'm looking at
GCWR 14,300
Max load trailer weight 8,800
I hope I am reading this correctly..
Tongue weight on this model trailer is stated at 825

The GCWR is a hard number. The combined truck and trailer should never exceed 14,300.


But the tow rating is a wet dream. You can tow a trailer that grosses 8,800 pounds without exceeding the GCWR only when your wet and loaded tow vehicle weighs less than (14,300 minus 8,800) 5,500 pounds. Your wet and loaded tow vehicle is going to weigh a lot more than 5,500 pounds, so your real-world max trailer will be a lot less than 8,800.


Also, the GCWR is probably not your limiter as to max trailer weight. GVWR (and payload capacity) of your tow vehicle is probably the limiter, if the max tongue weight your receiver hitch can have is not the limiter.


Another misleading spec. That's "dry" weight, but you won't be towing a dry RV trailer. Your actual tongue weight (TW) will probably be about 13% of the wet and loaded trailer weight. So if your wet and loaded trailer weighs 7,500 pounds, your TW will be about 975 pounds, plus another ~100 pounds for the required weight-distributing (WD) hitch, for a total of ~1,075 pounds of hitch weight. So that's about 1075 pounds you can reduce your available payload capacity. How much payload capacity do you have left for people and stuff?


I'm thinking you're right. If you don't want to be overloaded over any of the tow vehicle's weight ratings (GCWR, GVWR, rear GARW, receiver hitch weight rating) Then you probably need to find a much lighter trailer. Maybe something like this one:
http://www.dutchmen.com/coleman/floo...?modelId=24736


That one has GVWR of 7,600 and will probably gross over 6,600 pounds when wet and loaded for the road - with about 950 pounds hitch weight. To get a lighter-weight BH will mean going less than the "normal" 24' box length for a TT.


My TT with a 20' box and no slide is a wonderful little RV for two old folks and two dogs, but it's not enough room inside for a family.

Your truck's GVWR is 7000lb and you should assume you will max this out. So that leaves 7300lb for the TT (14300-7000). Given the GTWR is 8800lb, you have a 1500lb problem (and I am not even accounting for the weight of the Blue Ox). You are offloading the tongue weight onto the truck (it's accounted for in the 7000lb assuming you have the payload room) and you could only use up 1/2 the cargo carrying capacity of the trailer to keep under the GCWR limit. But you have no safety margin and do you really want to tow like that?

For comparison sake, I have basically the same truck with a 7000lb GTWR and still have to watch the cargo and payload #'s to make the towing tolerable.

I don't understand your numbers at all. It seems that your TT dry almost out weighs your truck. If you put anything in TT you are going to be way off. I need to see payload and I don't think it will be that much. I know you said 7000 GVWR for truck and some of the other pros say 8800. If 8800 is right then you still have issues. the way i see it is too much trailer for the truck. Just my two cents.

Tongue weight is part of payload. You can tow a lot more than you can haul.

What's the payload? It's on the door sticker.
The combined weight of occupants and cargo should never exceed XXXX lbs.
GVWR - payload = truck weight as it left the factory including a full tank of fuel.
