En español | Just recently, relatively few retirees took on part-time jobs. Today, the majority of retirees are working as a way to stay engaged, support a lifestyle or both.

For Jose and Jill Ferrer, ages 61 and 56, respectively, it's the whole ball of wax. When they retired from telecommunications careers that spanned nearly three decades at AT&T, they sold their townhouse in Randolph, N.J., for about $360,000 and hit the road.

Since 2005, they've traveled full time from Oregon to New Mexico to Florida and points in between at the wheel of their 40-foot Country Coach Allure motor home (paid for with cash). A Harley-Davidson Heritage Softail motorcycle, a Saturn car and two bikes are along for the ride.

"We're living a lifestyle that enables us to move around as we choose," says Jill. "We usually take our time — spending at least a few days and more likely a week or more in an area. We fully intend to get to all of the national parks."

The couple planned carefully for their retirement. They lived off one of their $100,000-a-year salaries for about five years before retiring and saving the other one. They contributed the maximum to their 401(k) plans and rolled them over into individual retirement accounts once they retired. And they expect to start taking Social Security when they're eligible. "We're hopeful that we have saved enough to last us in a retirement that includes frugal living and part-time work," Jill explains.

For the road warrior couple, that part-time work is a website and blog dedicated to the RV Lifestyle. "We were seeking something we could do on the road to make some extra income. We created Your RV Lifestyle as a site where we could share tips, lessons learned and travel experiences," she says.

And it has worked. With both a laptop and a desktop in the motor home, they use a wireless data plan with an air card for Internet access. On average, they try to do something on the site every day: a blog, a new page or an updated page.

The payoff: They earn a small commission on products sold through the product-affiliate programs related to the RV lifestyle, such as Good Sam RV club, FMCA, RV books/DVDs and so on, that are promoted on the site. They also get a cut when visitors click on Google Adsense ads displayed on the relevant pages.

"For now, as we balance various aspects of our life, we are happy to earn a little extra money — about $700 a month — from the site," Jill says. "And we know the potential is there to grow our website business further."

Whatever your reason for wanting to keep earning income, it doesn't mean you're locked into the daily treadmill. Opting to work a slimmed down number of hours a week gives you plenty of room to travel, enjoy your hobbies, spend time with friends and more.
