It's always important to note that a motorhome is based on a van chassis. Vans, by their nature, are designed to run up high mileages over 10-years before being be scrapped. They are not designed to sit around for six months standing doing nothing. Vehicles that are left standing for long periods are usually prone to corrosion, particularly within the suspension, exhaust and joints.

That said, the above vehicle may be fine if it's been dry stored and serviced regularly (with an oil and filter change every 12 months). However, if you do buy it, I'd recommend going in to the ownership with the expectation that the motorhome will need considerable work and money to keep it on the road for the next 10 years.
