As someone who was once in the trailer business, I wouldn't recommend anyone pull a trailer with either a PT or HHR. and if you do I would not exceed the rating of the car, in fact I always recommend staying at about 80% of the rating. One, most people underestimate the weight of their trailer and load. Two, I personally think the ratings are a lot of the time high. I have a Chevy Colorado rated at 5500 pound, I tried pulling about 4000 pound trailer, brakes on the trailer, with a brake controller in the truck. It would pull it but the truck was working hard. On my Chevy HD, it is rated at 12,500 pound and I try to stay under 10,000 pound. My 30ft toy hauler with 2 motorcycles in it is between 9500 and 10000 pounds, depending on which bikes I have in it. Boss Hoss's are heavier than Runes or V-rods. It pulls this load better and easier than the Colorado pulls the 4000 pound load. Long story short if you are going to tow, get a proper tow vehicle, Truck or SUV. Your Safety depends on it.
