[Jay & Bobbie]

We purchased ours from Facebook Marketplace.
Wherever you choose to advertise, be aware (as Jim said) buyers do a lot of research (we did). If you want top dollar, you must show why your rig is worth it.
Our seller offered a lot of accessories with the rig, provided all documents on things such as tire replacement, wheel bearing service, etc. and allowed us full access to it for several days to perform inspections. It was not the cheapest unit we were considering, but the best value.
