I have a 2012 Supercrew(157" wheelbase) 4X4 with the ecoboost and max trailer tow. My wife and I just purchased a Laredo 293sbh fifth wheel. I'm not concered with the weight of the trailer as the GVWR of the trailer is 1000lbs less than the max tow capacity of the truck. My concern is the pin weight of the trailer at 1650lbs dry. Our old trailer was a 28' fifth wheel that only weighs 1000-1500lbs less than the new one and we had no trouble pulling that one. So I should still be ok, right?

 

What is the gross of the new 5er? Figure 20% for the king pin wt.

What is a axle ratings on the truck.

What is the max load according to the sidewall on the tires at max PSI. E-rated tires or P?

 

What Scott said.

I can NOT get used to the idea of a 1/4 ton truck pulling a 30" 5th wheel!!!! I wouldn't sweat the PULLING..... I'd be worried about the STOPPING!

 

I think he will be over on the rear axle and tires personally. The 1/2 ton axles are not as robust as a 3/4 or 1 ton.

There is not going to be too much wiggle room.

 

Just think.......

There will be a Tundra owner out there somewhere towing a triple-axle because those optimistic numbers add up in his head.

Just wait until he finds out they are adding diesel power to their line of 1/2-tons.

Oh, joy.........

You know guys, maybe we are just getting old! At least I know I am!!

The only way you will know for sure is to get the whole rig to a scale and see what your numbers come in at, My guess is in line with the others that you will be over on your rear axle weight,,

 

Wait? They are doing it now. My family and I went to Fort Wilderness at Walt Disney World in October 2012. In our camping loop there were 3 Tundras with 5th wheel configurations. One of them was directly across my site! Maybe he didn't get the memo. I should have asked the owner why a 1/2 ton instead of a 3/4. Maybe the Toyotas trucks have something that we don't. What that is, I have no idea.

My wife and I like walking around the campgrounds looking at different trucks and trailer combos. Usually it is Ford DRWs or Dodge DRWs. However, the local CG seems to have mostly Chevys for towing. Probably because the owner knows those trucks are meant for short distance trips! LOL

 

LOL.... I don't know ANYONE who isn't!!!

 

Just got the truck back from the dealer, had it in for service. So I could check the numbers.

Here they are:
front axle- 3900lbs
rear axle- 4050lbs
tire rating- 2500lbs
payload capacity of the truck- 1840lbs
max tow rating of the truck- 11,100lbs
Trailer dry weight- 8300
dry hitch weight of trailer- 1650lbs
trailer GVWR-10,000lbs

Our old fifth wheel was pulled by this truck and it weighed 8500lbs loaded and I would put our 2500lbs boat behind it for one trip a year. I won't be putting the boat behind this trailer.

 

Those two numbers would give me great pause. Payload of the truck includes the weight of fuel, passengers and anything else in the truck. So between that number and the pin weight you have less than 200 lbs. to play with. That is not good no matter how you might count all the other numbers.

 

Another potential problem is projecting pin weight based upon dry weights, especially if those are manufacturer numbers and not real world scale weights. Some of these fivers are not close to published weights. I wish it were otherwise, but there is no substitute for running the whole rig up on a scale and see what the print-out says. My two cents.

What is trailer gross? Nobody goes around as built from the factory.

 

correct with one addition:

payload listed on the sticker includes a full tank of fuel, all optional equipment on the truck, and 150lbs for the driver.

so as stated, you have about 200lbs to play with, minus the difference in your weight and 150lbs.

you will likely be over your payload capacity once you get the trailer all loaded up. you may still have some room on your GRAWR, and your tires, but over on the total Gross.

just some thoughts.
