I have been in the process of installing a second A/C unit on my Impact Toy Hauler. Some of the instructions for the install from Dometic are somewhat vauge and I needed an answer. Enter our very own forum member....
Chuckster57, the man with a plan
and more importantly, experience and know how. Thank you Sir!
Next is a shout out to PPL Motorhome, where I purchased my A/C equipment....thermostat and control box, ADB, and actual A/C unit. The first unit arrived from them damaged from the factory...not by the shipper. They sent out a FedEx truck to pick it up AND shipped the new unit the same day....in other words before they got the damaged one back. Yesterday, as I was finishing up the install and was putting the Air Distribution Box up, I noticed that the unit had been cut on (read ...damaged). Apparently, someone else had purchased it, butchered it up a bit, and returned it for new. They must not have noticed it, and sold it to me in my original purchase. I emailed PPL yesterday evening (Sunday), and was hoping for a response this morning after they opened....and is got one very promptly. They are sending me another ADB TODAY.
The example above ^^^^^ even with the issues that I encountered, show that PPL Motorhomes is very willing to provide EXCELLENT customer service when something(s) go wrong. Mistakes happen with any company, but the thing that sets them apart is how they deal with issues when something goes wrong. In my one experience with PPL, I couldn't be happier with their level of commitment to making a satisfied customer.
