Just signed up. I have had RVs and 5ers most of my life. My wife, twin sons, and I live in a Recreation By Design 56' custom 5er. We are the 2nd owners. We are full timers now going on 11 years. Our hauler is a 1999 International 4700 530 lo pro with a Stalick conversion (only 72,000). I have owned it for going on 4 years. I plan on enclosing the hitch section to make it like a flat truck bed and storage when not in 5er mode, but easily removable. Here's my present problem: The drivers side gas tank when full will register at best 5/8 of a tank. I am pretty sure that it is the sending unit. What I would like to know is has anyone worked on one of these? Do you have any "short cuts" or instructions on best way to get to the sending unit? What part name and number Stalick used, etc? I have never let the left tank go empty to test the passenger side tank (It has an auto switch valve). That will be next. Is there a build sheet for these Stalicks, because I am finding buttons in the cab that have no markings to what they do or are for. Thanks again and really looking forward to learning.
