I hate to drive anyone nuts with my newb questions but I need some opinions.   I just bought a new truck and trailer BUT will not be able to load everything up and take it to the scales until the spring.  I've done my best to estimate if my truck and trailer combo are good but, I'd like to run some numbers by the good people here a HTW to see if I'm right.

The truck:

2008 Ford F-350 4WD Lariat Super Duty  with a 6.4 V8 Power Stroke, crew cab, dual wheels, 8' bed. Axle ratio is: 3.73

 Front GAWR: 6,000#.  Rear GAWR: 9,000# .  GVWR: 13,000#

Sticker says: The combined weight of the occupants & cargo should NOT exceed 4,356#

I estimated the MAX cargo and passenger weight would be 1,000# (not counting pinweight of trailer) Normally, we would be traveling with only two people and a big dog without anything in the bed of the truck.

5th wheel towing capacity  for truck as per Ford site is 15,200#

Tires: BF Goodrich Rugged Trail T/A, LT245/75R17  121/118,  R MTS,  Load range E.  MAX Dual 2,910# @80 PSI cold.

 

The Trailer: 2005 C&C 3 horse slant with 12' Showtime conversion. 8' wide, 7'6" tall. 27' on floor. There is a hay rack for hay and water tank.

From plate under neck: GVWR: 18,250

GAWR: 7,000

Estimated MAX weight of trailer, full tanks, 3 horses, feed, extra water, and everything else is 15,050#.

That number is MAX but I would normally only travel with 2 horses

Tires: Goodyear G614 RST Unisteel - LT235/85R16

EO3R 1064/123L, Load Range:G

DOT MJOR 610 W 1805

Max Load:: 3,750@110 PSI cold.

Other numbers.

GVWR trailer: 18,500#

GVWR Truck: 13,000#

 

MAX weight estimate of loaded trailer : 15,050#

MAX GN Towing capacity of truck : 15,200#

So, folks, am I good to go as far as you can tell without me being able to provide the weights at a scale?

Find a scale and roll across it to make sure.  Any of us on the forum are only guessing.

But if your Trailer max = 15050 and say 20% is on the pin. That equals 3010lbs  Plus the 1000lbs in the cab = 4010lbs which is less than the 4,356lbs the truck is rated for. So looks good there.  If your pin is 25% or 3,762 plus the 1,000 in the cab, you are now at 4,762 which is over your rated cargo load.

For the axles and tires.  15,050 less the 20% pin weight leaves 12,040 on the axles. Assuming you have 7,000 axles, You are good. Each tires gets 3010 which is less than what the Goodyears "G" rated tires carry, So you are good there.

I think you are good. The only close numbers will be what the pin weight is. If you are pushing that 25%, put your horses behind the axles in the 2nd and 3rd stall. Helping to counter balance the weight over the axles and reducing what sits on the pin.

But you really won't know until you load up and roll across a scale.

 Your 9,000lb truck and 15,000lb trailer combined = 24,000lbs  Which is still under the Federal GCVW of 26,001 lbs that requires a CDL

Thank you for the speedy reply.  I plan on carrying 2 horses in the last 2 stalls and putting hay and water on the roof rack.  I would hope that doing so would help with the pin weight.

In my state, it doesn't matter the weight of the load, but the numbers on the registration tags from the manufacture on the trailer.From plate under neck: GVWR: 18,250 plus the weight of the truck 9,000= overweight limit of 26,000 for non-cdl. If your state offers a Recreational Trailer license plate, I would get one. It is crazy what I have seen with RV plates in Illinois, last week I saw a huge semi with a full sleeper driven by a 70 year old man, it had an RV plate.

Your trailer tires at max load support less than your axle's ratings...so the tires will be the limiting factor for your trailer load...you need to go over a scale...because depending how your trailer is loaded will determine your actual axle loadings and whether your numbers are all proper...

Yes, I know I need to go over a scale but, loading up the whole truck and trailer and going across the scales only to go back home and unload everything makes no sense.  The trailer is already winterized (empty tanks) and I don't want to fill them back up just for a weigh in.

 All I was looking for was a best guess as to whether I have enough truck for my trailer. I purposefully maxed out everything but on average, would be travelling with about 1,500# less than I have estimated.

Thank you for the heads up on the tires, Paul.

You'll be fine. You have plenty of truck.

FWIW- Paul stands corrected on this. You state you have 7,000# axles. Your tires are LT235/85R16 Load Range "G". This tire is 3,750#/tires. That's 7500 per axle. So your axles are the limiting factor. No problems, just be aware. This is common.

Oops I was working off her TRUCK tires......Tires: BF Goodrich Rugged Trail T/A, LT245/75R17 121/118, R MTS, Load range E. MAX Dual 2,910# @80 PSI cold. Too many numbers in that message...

Thanks for your replies, everyone and Paul, like I said, numbers + even more numbers = confusion. LOL!
