a word of advice - never say "I'm just thinking about selling" or "I don't need to sell" or "I really don't want to let it sit for a few years" because it makes you sound like you're not really wanting to sell. For every one unmotivated-appearing-seller of you there's 200 on Craigslist that the people are very willing to sell. Simply saying "motivated to sell" or "selling to fund a world-travel-adventure" and a link to your bus will catch far more people's attention. Here's why, from my chair it sounds like you want to find a sucker to buy your rig - one that will pay way too much - even though, you've priced your rig competitively. The other issue is this, you can't sell to someone who won't come look. Saying you're not really motivated to sell doesn't get people to look at your rig - and find out that you've priced it very competitively.
And never post pictures of you wheeling your rig - it says "beat hard, put away wet." Believe it or not, I sold a pickup that had a winch on it - but it wasn't getting anyone to look at it. I took the winch off, put a regular bumper on it and sold it for $500 more - because the guy was convinced that the rig had never been wheeled (and it hadn't been) but with the winch on it....
heavens I hate psychology - mostly because it works.
GLWS, I'm jealous of your plans.
