Here is what I want to tow:

5,000 pound trailer (GN, 3 horse slant load, or 2 horse straight load)

Max of three horses (say 1500 pounds each = 4500 pounds).

I am trying to decide whether to get a 2500 or a 3500 in either the dodge or the Chevy.

I orignally wanted a GMC, but those are so hard to find.

5000 pounds + 4500 pounds = 9500 pounds without gear, tack, people, etc.

I have heard that the rule is to only tow 80% of the towing vehicles recommended weight for live cargo..... ie; The dodge 2500 towing capacity is listed at approximately 12,000 pounds.

80% of 12,000 pounds = 9600 pounds. (which is really close to what I want to pull).

I feel like, according to this rule, I am right on the edge of needing a 3500 truck, instead of the 2500.

Whew. Thoughts?

Hitch weight, hitch weight, hitch weight.

Like in the real estate arena... Hitch weigh governs the choice between a dually and a 3/4 ton truck. No matter if the manufacturer calls it a 350 or 3500. If it has only a single rear wheel axle set up, it's a 3/4 ton truck. Be very sure your loaded trailer will not overload the rear axle.

If you're on the edge, go dually for the stability and load factor.
