I have not purchased a motorhome from PPL, but have bought accessories (tow bar, etc etc) and find them very nice folks in that section.
They do carry a very nice selection of RV's.
You'll get a gazillion bits of advise on what to check out prior to purchase (furnace operation, fridge operation, ceiling leaks, etc etc) so I'll throw mine in early: look closely at the tires and read the date code. These danged things run anywhere from $200-$500 per unit!
You will have a ball with your RV. We have doggies and grandkids and the RV has proven to be the best toy we ever purchased. :-)
