In our 177 we have:
1. Microwave safe plastic for dishes, bowls and an unbreakable pot or two for microwave use. We carry two 8" frying pans - can cook in both at the same time on the tiny burners!
2. A shower stall curtain rod for inside the bathroom to hang towels on
3. A couple of throw pillows to make DVD watching more comfortable
4. A bucket (stores all liquids like soft soap, dish soap, etc so no leakage while traveling)
5. A tool kit with basics (duct tape, multi functional screwdriver, hammer, etc)
6. A first aid kit
7. A small container with "office supplies" in it - rubber bands, paper clips, pens, pencils, small note pad, tape, extra batteries and light bulbs, etc
8. A shower cap for the smoke alarm!
9. A small table lamp for lighting other than the bright lights
10. Silicone cutting board, trivet, kitchen scissors, dish drainer and mat, burner covers
11. Moisture resistance salt and pepper shakers, small spices.
12. Zip lock storage bags, foil and saran wrap.
13. Small garbage can
14. Water proof matches as well as propane lighter
15. Fire starters
16. Folding chars, in ground cup holders and a small table for around the fire
17. Outdoor lights - the goofier the better
18. Hot dog sticks and Mountain pie makers
19. A colorful clothes line (harder to leave behind if it's brightly colored) and clothes pins
20. Books on birds, reptiles and trees.
21. Cards, Uno and a few other small games
22. An axe
23. A small propane grill
24. Citronella candles
25. Bugle (my DH plays taps at sundown where ever we are)
This seems like a huge list but it all fits in our cupboards, under seat storage or the garage with room to spare.
Have fun getting your supplies together!
