I agree a dry bag for the tent is over kill. I thought of using it more as a stuff sack. Freezer bags for clothes is the way to go. I have tried Mummy down and can't sleep so confined so I am sacrificing wt and size with a more comfortable bag. I will be stopping at family 300 miles into the ride so any adjustments add/subtract can be done. I did GOBA last year self contained but I am still unsure. It will be my first long solo tour. I am a bit apprehensive but excited. Attached is a pic from GOBA which is my basic setup.
