I'm not sure when Liberty started offering slides, but to the best of my knowledge, they have only used Prevost slides.

Also, for my 2 cents worth, it is more important that you be happy with your bus, without the feeling that you "settled", than close proximity to factory service.

It's a lot of money to spend to be saying to yourself "I wish I had..." later down the road as you live with your choice.

Just food for thought....
