Hi Zeecarr:
Sounds like a nice trailer you have there and an easy tow w/ your Expy. What would you estimate the weight of your trailer when empty and total trailer weight when loaded? What was the MPG when towing your trailer loaded? We have NOT towed anything w/ our new 2024 Expy (w/ HD Towing) yet, but plan on a short 400 mile round trip in June with our 3-horse, slant-load Horse Trailer (but w/ only 2 horses), in tow. It's a tandem axle trailer w/ 4-wheel electric brakes and rated at 7000# gross w/ 3 horses & tack but, even w/ our previous V8 2012 Expy, we never hauled 3 horses at once so never exceeded 5500-6000# total weight. It is also a rounded V-Nose trailer on the front but flat doors on the back so, I guess that nose doesn't do much good for aerodynamics per, Left Coast Geeks knowledgeable explanations above.
Do you use a Weight Distribution Hitch or not, w/ your trailer? Thanks for your experience and knowledge, Lance.
Horse trailers carry their weight differently than utility and rv style trailers. The horse trailer axles are pushed back farther like a boat trailer.
It all depends on how the trailer balances the weight. Also depends on the horses! My quarter horses I grew up with were huge horses. 15-17 hand cattle ranch horses they were beefy boys heavy! Plus the tack we loaded in the nose of the old trailer. That thing was no joke regarding weight.
I’m not sure how the tongue weight plays on those trailers I quit horsing around with horses in college many yrs ago.
I can tell you my 8700lb boat with the trailer axels set way back were probably 60% of the weight is makes it really important to watch how you load the front 1/2 of the trailer regarding tongue weight. Having said that!!!
Trailers with the axles pushed back to the rear of the trailer are massively more stable than trailers like the RVs and utility trailers where you have considerable trailer behind the axles.
So my suggestion would be get a tongue weight on the horse trailer. Too much definitely lifts the front tires off the ground making turning and stopping impossible!! Don’t ask my boat wasn’t fit correctly when I picked it up. Shoved all the way forward on the trailer. Front tires literally were off the ground

. I had to work on getting the boat bunks and bow bracket moved back to get the boat correctly fit to the trailer and sensible tongue weight. The Expedition will squat 2-2.5 inches empty with 800lbs on the hitch. If your pushing 3+ inches of squat you need to check tongue weight and get weight distribution bars .
Thats where weight distribution bars come in to cheat the game some by levering pressure onto to front end.
If you get that sorted? I wouldn’t go more than 960lbs and if your getting that high? Definitely don’t be loading the back of the Expedition with gear and people. This is where the 2600-3000lb cargo in the bed capacity matters in the F250 type trucks.
Its not the trailer weight its your load weight on the tow rig. Gets you long before you max the tow rating.
Once towing lock out gears 8-10 so your only using 1-7. You will most definitely need to max your trailer brake gain to 10. In addition stopping will take you 4x the distance!!!! Not joking…. Plus you have horses drive like a 100yr old grandma with cataracts. Slow, gentle and smooth.
