Question after CAT scale results

I have a question for those that have more experience than I when it comes to CAT scale results. I have money down to hold an F250 after my first tow in our new TT with my F150. Before I sign the paperwork for the F250 I want to make sure I'm reading the numbers right. I feel my F150 is close to its limits. What do you think? Thanks!

Current TV: 2015 Ford F150 Supercrew short box with 3.5 ecoboost
GVWR 7000#
Payload 1900#
Front GAWR 3375#
Rear CAWR 3800#

Current TT: 2018 FR Rockwood 2706ws
GVWR 8073#
Payload 1486#
Length 32'10"

WDH: Equalizer with 12000# bars.

CAT results of TV loaded, no TT attached 5746#
CAT results with TT attached to TV and WDH in place:
Steer axle 2980#
Drive axle 3700#
Trailer axle 6180#
Gross weight 12860#

Need the full set of CAT results for both with and without trailer to really run the numbers, but let's look at it in a different light:

The fact that you've put a deposit on a F-250 means you felt something was off about towing with your F-150 right? If you're not comfortable with F-150, no amount of us saying "It's ok" is going to change that. If the F-250 makes you more comfortable, go with the F-250, provided you can afford it of course.

You are within specs, but I agree with Kaadk; you had a reason for putting a deposit down, so you should probably go with your instincts. I'm towing a lighter 28' TT w/ a Durango w/ similar specs to your pickup GVW 7100, front axle 3200 rear axle 3900. and we're staying within 5 hours of home (no mountains) until i get a chance to get a pickup.
Good luck with whatever you decide.

I'm looking at the new truck so I can tow safer and carry more payload if I desire. As is, the TT is nor loaded up much and all the tanks are empty. According to my figures I'm pretty close to GVWR on my TV if not slightly over.

You left out the one of the most important numbers which is the

GCWR of your TV. Do you know what that is? Sometimes that number is lower than your individual ratings.

With the information provided so far, below is what the current numbers look like. In order to determine if the truck, trailer & WDH are truly well matched, we need the individual axle weights of the truck without the trailer and then the truck with the trailer sans WDH bars engaged. Doing so will allow you to see the weight on each axle and overall weight to determine if your truck is truly overloaded.

Honestly I think your trailer is paired decently with your truck. I would start looking at tires/hitch/loading adjustments but I have many thousands of towing miles behind me with a very similar rockwood 2701 using 2 different F-150's.

It is amazing what a hitch adjustment, or hitch upgrade can do. A fully loaded trailer at 7114 pounds is half ton towable.

The weights without the WDH in place are not relevant unless one plans to not use the hitch.

The OP weights with the TT hooked up show the truck is 320 pounds below maximum weight. More importantly, the rear axle is 100 pounds below max. Adding passengers, gear and gas is going to eat into the 320 pounds of available useful load pretty fast and depending on load location could overload the rear axle while still being below overall max weight.

The configuration and weights as posted are definitely below the truck limits. My previous 1500 truck had very similar numbers although the the TT is much heavier. The biggest problem was stopping a 9,000 pound trailer with 1930s technology brakes. Solved that issue by putting hydraulic disc brakes on the trailer. I upgraded to a 2500 in order to have more stability. Driving the length of Oklahoma last week with 20-30 knot quartering crosswinds would have been an issue with the 1500 but the 2500 handled it just fine.
