In general, if you're looking for a good 1/2 ton tow vehicle, steer clear of 4X4's or top of the line trims. Both eat up the payload. Also, SUVs will have squishier suspension, which is not ideal for towing. Trucks are a better option unless you have a really good reason to stick with an SUV (and then know you will be making trade-offs).
