Wife & took a 150 mile (or so) test ride last weekend. Nice warm sunny day, so we were happy to have the AC up & running. Worked very well, thankfully. Controls worked well , under dash vents made blocking or changing air direction easy. Once initial cooling of the cab took place, then AC was run mostly at very low speed. Really does a nice job.
Had some of the peel & stick insulation I'd used on the firewall left over (Shown in earlier post), so I installed the rest on underside of the hood. Seems to help with engine noise in cab.
We're planning a approx 2000 mi trip with the c10 in late May/early June, so we're using these test drives to find anything that needs help. I thought the wife would want a quieter exhaust, for example. But she says she likes it as is. Most drives have been on non interstate roads , so speeds have been 60 mph or less. We did about 10 miles of interstate at 70 mph on this latest test drive. Cab noise seemed to greatly increase, but truck did fine otherwise. At 60 or less, normal conversation possible, at 70 mph it's not.
The plan for the upcoming trip is non interstate roads, but we can do the big road if need be.
