Preparing for a longish drive

We were planning a longish drive for Thursday, from Cape Breton Highlands to south of Halifax, a little over 300 miles, and we know that the first part of it will be challenging as it is the road that we drove on Sunday which is narrow and curving and had deteriorating edges. 

One of the inner duals (on the driver's side) is losing air at a slow rate - so we decided to air it up on Wednesday evening...

Carl checking the current pressure in the tire.

Adding air from the onboard air from Gracie.

Thankfully we can use air from Gracie -- we did need to start her up and let her reach air pressure, which I'm sure our campground neighbors appreciated (not!). The onboard air works pretty well for Gracie's back tires as our desired air pressure is about 80-85PSI. It is harder to put air in the front tires as we run about 100-105PSI which is pretty close to the max pressure that Gracie's air system will maintain. We got the tires at appropriate pressures ready for our drive on Thursday.
