Im local to PPL - the staff i have encountered (by phone, internet/email & in person) were very helpful and polite - that said i never really dealt w/ any of the RV Sales folks. I deal mainly with parts folks and have had conversations w/ finance (once).
there are HUNDREDS of each type of RV...and as has been said here before....condition runs the gamut. Its a self service type lot....dont expect anyone to walk the lot w/ you or to know the condition of a unit - there are just too many units and the turn over is pretty rapid.
id be happy to go look at a unit and provide an over the phone evaluation/feedback - but you can expect me to tell you everything i see wrong w/ the unit (in the interest in full disclosure).
I can take some pictures if you like (perhaps this should be a business).
PM me & I we can swap emails / phone numbers & arrange a time for to look over any units you want me to look at.
