2 things about heavy bags- YOU generally have to CARRY the bag to your tent which might be a long ways away from the truck. And when you are tired, it's not fun. You also have to CARRY the bag AND your tent BACK to the truck the next morning. So, keep it light if you can.

I also recommend that you put air in your tires when you get in from the day's ride. Otherwise you will have to wait in the morning sometimes 1/2 hour or more to get a pump. I was lucky- only had to pump my tires once that entire week. BUT, do check the pressure daily. You must ride at 100-110 lbs minimum.

On that note, I hope you all have good tires. If you don't, now is the time to get them on your bike! Your goal for the ride- no flats. Start with good tires and the recommended tire pressure. Flats occur when you don't have enough tire pressure, bad or worn tires,bad tubes, and of course, unforeseen junk on the road. So, you can prevent a lot of misery by being proactive in this regard.

On that note- pack in a couple of spare tubes in addition to the one tube you take with you at all times. IF you have a flat, you can save the flatted tube and replace it with a new tube for your spare the next day.
