I know little about MHs but a 2011 unit could had been sold in early 2010. As you read more on the forums you will see that many members already have 2015 units that started coming out around March or so.
It's also common for people that are retired to more traveling which puts mileage on.
Also recommend getting an used RV inspected prior to buying. Don't depend on the seller to share information.
Great choice for "Living within my means" and camping for one...
