Doing a little tour of the South, and have everything all mapped out, but wanted suggestions on how to pack.
I've decided to stay in motels
Total capacity is 104 liters via Givi E52 top and 2x Pelican 1520s (plus a bitty Manta tankbag):
Heck, for that trip, all I'd need is my tankbag. It has sunscreen, wipes, OTC drugs (decongestant, painkiller, etc), toiletries, basic first aid, bottle of water or Gatorade (replaced every gas stop), soft cloth and soapy water for cleaning glasses and visor ... that's about all you really need. If it's over 500 miles, add chain lube. Around here, I'd have a heavier pair of gloves for the mountain passes; not really a problem in Texas.
For an overnight, you can even get by with no spare clothes if you wear the right clothes. Choose sportswear, no cotton, synthetics only -- the good stuff can be washed in a sink and will be dry before morning, especially if you hang them near the air conditioner. Since you've got a trunk, an extra change of clothes will save you some trouble. For an overnight, don't forget some footwear, so you don't have to walk around in motorcycle boots!
Travelling light is easy once you get used to it. If I'm not camping, I can literally just gear up, grab the tank bag, and hit the road.
p.s. DO NOT forget to re-sunscreen any exposed skin at every gas stop. A sunglasses-shaped pale spot around the burn on your face is pretty embarrassing. I learned this last year on I-10 in west Texas.
