I have several trailers (box trucks) for sale. If any of you guys are interested please e-mail me abelwash@comcast.net or call 800-485-1076...... I have come up with a unique way to set up wash units..... I have not found a manufacturer that sells units this way. Unfortuatley these ideas are very proprietery.... However all of my units are complete and in great working condition.... They are money making machines..... If you are new or just need an upgrade you MUST get in touch with me. These units need no work...
