A major area for concern on all VW Campers are the front wheel arches and inside the fron wheel arch itself.
The Front arches are very prone to rotting away. A big problem with this is that over the years these get bidged up and people end up either filling them or sticking a cheap outer repair panel on them. These are awful and simply hide the rust and rot underneath.
If your are considering buy a van make sure it has had complete fron wheel arches fitted. If your van need front arches there are two options.
1. A replacement Complete front arch
2. A Genuine VW complete front arch
If you want to spend a couple of days fitting the arch then buy the replacement. If you want it to fit and be of a decent quality BUY THE GENUINE arch. These are a bit more expensive BUT will save you hour and hours of labour guarenteed.
