There's a major problem with SUV's and trailers. A lot of SUV's are at or nearly at their rated max weight. When you find one you are interested, best look up online what their curb weight is and what they are rated for. All that extra steel in them doesn't leave a lot of room for hooking up a trailer.
The other thing mentioned up above is wheelbase, the shorter the wheelbase the more pry a trailer will have on you. Staying away from any short wheelbase vehicle is optimal even if it has the ponies to tow.
First off-check again on the Expedition WITH THE TOWING package. THere is plenty of room to hook up a 2 horse BP. Tongue weight also factors in with trailers, not just the axle weight.
Here is the towing package I referred to:
Heavy-duty trailer tow package
Expeditions equipped with the heavy-duty trailer tow package are prepped and readied for towing at the factory. The package includes a heavy-duty V-5 rated Class IV trailer hitch with weight distribution capability, heavy-duty radiator, heavy-duty auxiliary transmission fluid cooler, hitch mounted 4 and 7-pin trailer electrics connector and factory prewiring for an electronic trailer brake controller module. The brake controller wiring harness is located under the dash on the driver’s side for easy installment of the brake controller module.
Expeditions are also offered with an adaptive electronically controlled pneumatic suspension system with self leveling, payload leveling and trailer load leveling capability. The pneumatic suspension can automatically detect when a heavy trailer is coupled, such as a travel trailer, and level the load. Additional sensors placed on the left and right sides of the SUV also monitor and compensate for any listing caused by improper cargo loading. This keeps the Expedition running straight and level while towing, and at night helps to keep the Expedition’s headlamps from blinding oncoming traffic.
As of the 2010 model year, the Expedition received trailer sway control (TSC) as standard equipment. TSC builds off of the AdvanceTrac traction & stability control system to detect trailer oscillations and corrects it via asymmetrical breaking and reducing engine power until the Expedition and its trailer are both back under control.
And here are your weights:
Over the years the Expedition’s towing capacity has grown from 8,100 lbs to a current rating of 9,200 lbs (when properly equipped). The list of towing features is also ever growing. Towing features common to all generations of the Expedition include: smallest possible turning radius for increased trailer maneuverability, large side view mirrors to improve rearward visibility, side view mirror rearward-facing lane departure/turning indicator lamps, which are helpful to other motorist when the Expedition is towing a long trailer providing added visual safety, heavy-duty flashers, heavy-duty large robust disc brakes to withstand prolonged braking while towing and an available heavy-duty trailer tow package which includes necessary additions for heavy-duty towing.
WHen I referred to wheelbase, I was referring more to WIDTH, not length. The extra width gives you a more stable base.
