just got my badsquatch last night- tires were at 39psi and the ride was incredibly harsh - today, when it warmed up outside, they were at 46psi - so I dropped them down to 37 and will try that.
Don't kick yourself in the nuts, life also has a learning curve that needs to be calibrated from time to time....I just drove my 22 WT from Cali to AZ n the pressure on my tires was set at 45 psi, got great mileage, but it sure felt a bit bumpy at times (20 mpg) 2.7, I just lower the pressure. Going back I might increase it again, or just leave it at 36 psi.
