Motorhomes with aluminium outer skin?

Some of the older Monaco coaches had aluminum skin, which included their Holiday Rambler line. Many of the fiberglass coaches have had delamintation problems. I am not sure that a fiberglass sidewall is any cheaper to repair than an aluminum sidewall if you have severe damage.
Even the Monaco brands with the aluminum sidewalls had a fiberglass front and rear cap. Aluminum/stainless steel front and rear skins might be limited to just the Prevost chassis.
