Yeah, a 3 to 5 year ild unit with less than 50k miles can be had in the 190 to 250k range from what I've seen.I live in the town where Foretravel motorhomes are built, and I know folks that work there and sell them. Unless you’re buying a used older model, I seriously doubt $300k would even get you close what you want.
In this economy, toys are selling cheap barely used.
Same with boats and guns.
I could spend 500k but why, if I don't have too...
