Our "seven passenger van"! A 1978 GMC Royale. GMC made 12,921 motorhome between 1973 to 1978. The motorhome has a front wheel drive transaxle with an Olds 455 (7.5 l) or 403 (6.6 l) V8 engine. GMC used the turbohydramatic 425 transmission. Our baby has the Olds 403 V8. The Royale started as a transmode model(no interior) and finished by Jimmy Motors. We bought the motorhome in Idaho and drove it back to California with only one minor incident....overheated in Vegas.
