Where to sell, Where to sell?

I have a project planned for this summer.
I think I'm finally going to get around to it.
It is to clean and organize my storage unit.
When the hubby and I were married, one of our first purchases was a big long old reffer trailer.
It became our storage unit.
And what a lifesaver it's been.
We started out our life together in this lovely camper.

And two years ago we upgraded to this trailer house.

So that storage unit has been wonderful, I've actually had a place for a deep freeze, food storage, basic storage, ect.
But it also has a bunch of unneeded stuff in it.
So my mission is to go through it and organize it.
So my question for you is...
What's the best way to try and sell the stuff before I just donate it?
Craigslist?
Garage Sale?
KSL?
Facebook?
Any other suggestions?

Thanks for your help!

My Kitchen

This week I've been busy cleaning, cleaning, and organizing my kitchen. Koda gave me a hard time yesterday. He's all "Your about ready to pop out a baby, and here you are super cleaning this kitchen." Yes so I'm a woman, I'm pregnant, and it's Spring, give me a break. So I've done the different organizing challenges posted here pertaining to the kitchen as well as all my other cupboards countertops, ect. So here's the before and afters to prove it!

The pantry I cleaned and organized earlier this month, so I can check that off my list, although I do have some new idea's on how to orgainze it now.

The Freezer and the fridge will be done at a later date. I just filled my freezer up with a bunch of meat, going to wait till this fall when it's emptier and I'm a bit less prego to clean it. The fridge I plan on doing next week. Now onto today which is the dresser drawers...or in my case going through the girls clothes and bringing out baby clothes to put into the "new" dresser we have. Have fun today!!

Weekend Fun

Even though the weather was kinda miserable we had a fun productive weekend. We helped my family shear sheep. The girls LOVED it. Here's some fun pictures from the weekend.

Also my organizing challeng pictures. The challenge was to clean off and organize the computer desk. Well seeing how I just got a new desk and its all cleaned and organized, I thought I would do the desk area were the computer use to be, the baby is going to be for a few months, and maybe one day I can make it my crafting area.

Organizing Challenge

Lately I've been really drawn to organizing blogs. Probably something to do with nesting eh?
Well so over here at A Bowl Full of Lemons she had a 21 Day challenge at the first of the year. Well I'm going to do it. I'm due the thirtieth...21 days away...perfect. I started it yesterday figured it would help to give my need to organize some direction, so I wouldn't get feeling overwhelmed and then depressed. Now I know the baby will come whenever (I'm actually hoping she shows up a little early) so I'll be doing a few challenges on the same day. So lets go!! Here's her button to hook up, I also have it on my sidebar.
And now off to challenge #1 The Junk Drawer. In my case it is a Junk shelf, seeing how I only have two drawers in my kitchen area and those are used for wash clothes and towels and cooking utensils. So here's my collage of before and afters.

Looks much better huh?
