I'm a complete noob, and would appreciate any recommendations you guys could make to help me out:

I plan on taking 5 weeks to motorcycle across the country: down the east coast, and then across the south.

Lowest temperatures I should experience at night would be around 45F in the NE, and it'll likely average in the 60's when I'm in the south. I'll probably occasionally stealth camp as well. I'm looking for the best bang for my buck equipment.

I'm looking for:
- a compact and very easy to setup hammock which includes a good rain cover (Warbonnet Blackbird or Hennessy seem to be highly recommended?).
- recommendation for a compact sleeping bag I should get. Do I need a foam pad?

Since I am unlikely to experience anything below 40F, will I be warm enough with just a sleeping bag? Or do I need a foam pad for insulation as well?

This community rocks. Thank you!
