We own a 2000 Chinook Baja 4x4 with the Quigley conversion. It is very similar to this one that is currently for sale. For 2 people it is wonderful. Full wet bath, kitchen, 4K Onan, king sized bed, heated grey and black tanks,12k winch, A/C, solar panel, forced air furnace, etc. Ours has a Triton V-10. We run A/T Toyos . Over the last year, (on the highway) we average 10-12 mpg at 65-70 mph. 7-9 mpg around town. We have owned 6 previous rigs, 2 Big Foots, 2 Alaskans, a 4Wheel pop up, and a 36' RV, this is by far our favorite. FYI-I just checked the ad and it is no longer up. I have a feeling that this is a scam or hoax of some kind.Nice. Bet that gets about 7MPG.
