That sounds like one I had and wish we could have kept it. We liked the size and the rear queen bed was what we prefer. Not finding a DL model in the parts listings, though. Should be a label under the drivers window with a bunch of techie info, if you do want to verify for some reason. I find the most likely area to be ignored and possible bad shape are the batteries but they are also pretty straightforward to find the problem and replace at a somewhat reasonable price.
If you are able to access this site:
Tons of potential useful info if you get a specific model to match? Sometimes knowing what the parts look like is step one to getting them apart!
