Allvan has been building moving vans and curtainsiders for a long, long time. The former owner of Allvan opted not to pursue an R&D initiative to build our own rollback kits because there are a number of quality manufacturers in the market. Instead, we allied with Brian Petelka and LCS. Brian has designed and continues to re/design some of the best sliding systems on the continent. His kits and part designs are innovative. He supports his systems well. Brian has a passion for what he does, and Allvan is excited to be a part of the LCS family of distributors/installers. We know what and how we do the voodoo we do…we are also blessed to now offer you the same Petelka voodoo. Two voodoo.
