You might find the EXPED DownMat 7 DLX pad is worth a look - it should be big enough for you, it's super comfortable and its insulation is just outstanding (uses down to achieve this). It's amazing how much more flexibility you have in your heat management when heat loss to the ground is significantly reduced (eg lighter sleeping bag). Not cheap though. Weighs just over a kilo. Easy to pump up. This is our personal choice for touring. My business has had a look at the mats on the market recently and we chose to sell EXPED. We're located in Australia but there's bound to be an EXPED dealer in AZ. We're in the middle of reviewing sleeping bags, don't have a recommendation for you there yet.
