We just bought a 28BH-S. We are pulling it with a 2003 Ford Expedition, 4WD, with the 5.4 liter engine. It has the full towing package. So far I have only towed it from Sacramento (where I bought it) to Fresno (where I live). I was surprised at how much it caused my SUV to really get sluggish. It almost appeared as though the trailer was too much for the SUV. Before I bought the trailer my car dealer, the trailer dealer and several friends told me that I should not have any trouble towing it. Did I assume too much?
