2005 C4500 FIXING WHAT GM & MONROE SCREWED UP!PT1

THIS IS GOING TO UPSET A LOT OF FOLKS BUT HERE IS THE REALY....THIS TRUCK HAS NEVER HAD THE POWER AND TOQUE THAT A TRUCK THIS SIZE SHOULD. IT DOESNT TOW WELL. FUEL MILEAGE IS AWFUL. THE MONROE DUALLY BED IS MADE POORLY. THE OUSTSIDES ARE FIBERGLASS AND WAVY. THE BED IS TOO HIGH FOR ANY PRACTICAL USE. I AM ALWAYS WATCHING MY TRAILER DOESNT SMASH THE TOP RAILS WHEN I HAVE A GOOSENECK OR 5TH WHEEL HOOKED UP. THE BED MOUTING SUB FRAME WAS CONFUSING TO ME. SOLID MOUNTED IN THE CENTER AND A SINGLE RUBBER MOUNT FRONT AND BACK. THE TRUCK RIDES AWFUL. THE "LINK" REAR AIR SUSPENSION ENGINEERING AND GEOMETRY COULD HAVE BEEN DONE SO MUCH BETTER. USED THE FACTORY BUMP STOPS AND A SHORT AIR BAG. THIS LEFT LIMITED TRAVEL. THE TRUCK WAS CONSTANTLY BOTTOMING OUT ON THE BUMP STOPS. SHORT AIR BAG WITH LIMITED TRAVEL REQUIRES MORE AIR PRESSURE TO KEEP IT FROM BOTTOMING OUT....MORE AIR PRESSURE IS A ROUGHER RIDE. THE BRAKE WARNING SYSTEM ON THESE TRUCKS IS A CONSTANT ISSUE. THE BRAKES THEM SELVES ARE GOOD AND HANDLE A LOADED TRAILER WELL. SO HERE WE GO....WE ARE GOING TO BUILD THE TRUCK THAT GM SHOULD HAVE! THIS IS GOING TO BE A VERY LONG VIDEOS SERIES AND TAKE AN EXTREMELY LONG TIME TO COMPLETE. IT WONT BE CHEAP BUT IT WILL BE WHAT I NEED AND WANT THE TRUCK TO BE. THE BIG QUESTION STILL REMAINS......IS IT ALL WORTH IT?
