We picked up a 2017 HT28.5 last week.
Now I realize that it's used, but was told that the service dept. would inspect it prior to delivery.
Just checked the tire pressure. All 10 - 15 lbs. under 65psi. Except the spare: That was 23psi! 42lbs under pressure. I could have blown it up higher with a bicycle pump. Probably hasn't been checked since it left the factory.
My long held faith in RV salesmen and service departments has been shattered.
