Kenny, welcome to the site. I can't talk to the value proposition for your coach, it is a personal choice. Cost/ Benefits/ Options; these are things you have to work out. Regardless of what others might think of level of engine noise, comfort, build quality, condition of rig, you really need to do your due diligence to ensure you are satisfied with the purchase and it meets your needs. I would test drive it in multiple environments, local roads, highway speeds, large hills if available to go through the full range of sound impacts.
Never assume. Inspect and test. some three year old coaches will be sorted, others will be problem children the PO was desperate to rid themselves of.
It is a large $ purchase, put some time into verifying it meets your needs and is not a problem waiting for a place to happen.
