I just purchased a Super Air Nautique 220 that weighs approximately 5,000 pounds including the trailer. I'm looking for advice for a tow vehicle. I live in Central California where Summer days are around 100 degrees. I intend to keep the boat in the valley, but would like to tow it to a local mountain lake at approximately 5,000 feet. I need a vehicle has the power to make the tow up and the stability to bring it back down the hill. My wife is willing to let me trade-in her beloved Cadillac SRX for something we can use for towing, provided it is a high-end trim level. My guess is she'd go for an Escolade or Tahoe, but I'm not sure either will do the trick. The other option I'm thinking is to find a used, high mileage vehicle that I use only for pulling the boat up and down the hill. Any and all thoughts/options will be greatly appreciated. I suppose I should have thought about this before I bought the boat... too late now.
