My old
B8200 was similar in size and weight to your
B2400. I have a Carson 16' 7000lb trailer, dual axle. It has brakes on one axle(I want to add to the second axle).
My trailer is 1600lbs. The
B8200 with loader and scraper was about 2300lbs based on tractor, loader , and scraper data. Add another 100-200lbs for chain, binders, and "stuff". I was running ~4000lbs total.
That is well within the Tacoma rating noted.
I would maked sure you have a solid hitch with the ratings you need. And, make sure you have a good brake controller.
I would be cautious driving, and you would probably be OK.
FWIW, I have had to make a couple emergency stops after being cutoff by little cars zipping across lanes with no regard for those around them. Fortunately, I left safety room. Even so, I could really feel that trailer, even behind my 3/4 ton. Strange feeling, panic stop, anti-lock brakes activating, and feeling of the trailer behind you. That, is one reason I like my 3/4 ton, even though I do not run it to capacity most of the time.
