I bought my first DP from them years ago. Found it on their website, flew into Houston (from Cali) and rented a car. Looked at the rig and it had some minor issues that needed attention. We negotiated a price with the owner thru the dealer and came to an agreement. PPL put in new batteries from their side of things. They allowed us to "camp" in their parking lot..(three spaces all FHU) for two nights while we worked out any kinks in the coach. All in all it was a pleasant experience.
They leave all of the rigs unlocked so there's no high pressure with a salesman following you around. Inspect the coaches at your leisure. They do not wash or clean the rigs, that's up to the owner/seller. If there's a specific rig you're interested in, have an independent inspector look at it for you. IMHO, money well spent. Then again, the cost of the inspection would probably pay for your air fare to Houston and you'll get a mini vacation out of it to boot...:W.....Dennis
