Executive Dennis' above post is right on. We sold our motorhome through them and it was an easy carefree experience. We named our price which was a bit higher than PPL first recommended. They detailed it free and did an excellent job. A couple from Florida flew in and bought it. All this happened within a months' time.
There is absolutely no pressure on future buyers. When a buyer offers a price, PPL contacts the owner and it's up to the owner to accept or refuse it. PPL is not in the mechanic business so they won't do major repairs, if needed, but they will have it done elsewhere if that's what you agreed with the seller. PPL is basically a used RV storage lot. They give the seller the space to park it but they don't aggressively try to sell it.
When we were there we could not believe the amount of traffic that goes through there - folks bringing in their RVs, folks picking up their newly bought ones, and many, many lookers.
We were recommended to them by various friends who bought and sold through them and we were not disappointed.
Yes, you will see some junk there but it's not because of PPL it's because the owner's don't care for their RVs. Some will say they don't like the idea of leaving the slides out. I disagree. If it rains I want to know if there are any leaks. I don't want it hidden. When we RV we don't bring in the slides when it rains.
Again, there are good and bad units on the lot. Do your homework.
