In Colorado, there is no formal grace period for a Commercial Driver's License (CDL) after it expires. Drivers are required to renew their CDL before the expiration date to maintain their driving privileges. If the CDL has expired, the driver must go through the renewal process, which may include retesting. It's advisable to check with the Colorado Department of Revenue for specific guidelines and requirements.
You'll need to get a medical waiver in order to do this.
Getting the CDL back won't be a problem. Finding employment probably will be, though.
Getting the CDL isn't the problem - it's finding someone who'll hire you which is where your problems begin.

Yes. If you're moving to Colorado, the state requires you to exchange it for a Colorado license within 30 days of establishing residence, although it's not that strongly enforced... I moved to Colorado in November of 2010, but didn't exchange my North Carolina CDL for a Colorado one until April of 2011, with no penalties.
The most popular answer seems to be 5 to 7 grand.
If you are aware of the laws and have had practice, you can always try to get your CDL without taking a class. It's definitely not recommended though and would be better to help you pass it the first time by taking the class.
For private use, no state requires a CDL for an RV.
Federal law requires applicants for CDLs to take physicals and be drug tested.
Canada. Maybe Mexico. Anywhere else you go, your CDL won't be considered valid for operating a heavy goods vehicle in that country, and you'll need to obtain the local equivalent.
