This 1990 Winnebago Warrior was purchased a year ago from a truck driver and I have never seen an RV park. I have put 3,000 miles on it driving once back and forth from Florida to Wisconsin (and I stayed in hotels). It is in very nice condition and it has a Toyota V-6, 3.0 engine and an automatic transmission.
I was told (but I never verified that the V-6 engine will give you between 11 and 15 miles per gallon. I was also told that the RV will sleep 6.
To my knowledge, there have not been pets or smokers in the RV. I know virtually nothing else about the RV other than the fact I have never used the bathroom or shower. I have concluded that I am not a camper.
