Cadillac

I just purchased a 2720. I will be picking it up on Saturday. My current tow vehicle is a Dodge full size van 1500 with the V6. It has a 3500 pound towing capacity. I am sure this will be adequate because I live in WI and will not be traveling out west until I replace the vehicle. The V6 is under powered and would have difficulty pulling the steep grades. My actual question is when we replace the current tow vehicle we are considering a Cadillac SRX. It is the Cadillac cross over. We like it because it is a decent size, is RWD, and is rated for 4500 lbs for towing. Most crossovers are FWD based for towing something that heavy I would rather have RWD. Has anyone towed with one of these? Does anyone know of any issues with these vehicles specifically or Cadillacs in general? I mostly have driven Mopars because I am accustomed to their quirks and issues.
