I've been very pleased with my 2000 GeorgieBoy Landau Dp, and with my 1990 GB (31 ft gas) prior to that. I have not seen the Bellagio, but is a higher end- bigger equipped coach for Georgie Boy..
The Owners manual for the Bellagio is here, just enter the year and select.
Owners Manuals - Coachmen RV
Georgie Boy Mfg was bought out by Coachmen at some point, for years they existed as a separate entity, and later they physically combined with Coachmen at the Middlebury, IN facility. (My 2000 Landau was built in Edwardsburg, MI by GeorgieBoy, but the brochure at that time indicated Georgie Boy was a wholly owned subsidiary of Coachmen Industries)
Hope this helps.
