  1. Somewhere in the forum there is a floor repair post. Glued the new plywood down and then drilled 3/8 holes through the new wood and 2/3 of the way through the old floor, made the holes in a grid. Jack the old floor level then coat 3/8 dowels with epoxy and drove them into the holes. Let everything set up, flush cut the dowels and then sanded the floor. 

    Very rigid 

    Idea is new screws will pull out of the old floor, hammering the epoxy coated dowels in forces the epoxy everywhere into cavities in the old floor, much stronger.

    EDIT found it...https://toyotamotorhome.org/forums/index.php?/topic/10066-87-sunrader-floor-project/#comment-93485

     

  2. These are some VERY general thoughts on the "Sunrader sag". The design of the floor is OK, but the frame support design is the weak point. The failure mode is there is minimal support from the chassis to the edge of the shell. Over time the foam in the floor fails and the weight of the shell causes the edge of the floor to sag.

    To prevent the sag from coming back you need to add support from chassis to the edge of shell.

    Here is ONE answer...https://toyotamotorhome.org/forums/index.php?/topic/11856-sunrader-floor-repair-gut-and-rebuild/ 

     

  3. Remove all the fan belts, start the engine. This will tell you if the noise is in the engine or in the stuff bolted on.

    The #1 noise from the front of the engine is a timing chain tensioner failure. The cam cover needs to come off to check things out. A faliure will result in the timing carving a hole in the front cover, which has coolant in it. Keep engine running to a minimum until you find the noise. 

  4. There is a very long post about the brake bias valve. 

    Basic thing is because its supposed to be a pickup truck and its now sitting level, so the bias valve thinks that the pickup is empty and sends most of the breaking force to the front brakes.

    The higher the arm is the more brake is shifted to the rear. A lot of people just unbolt it from the bracket on the axle and bolt/bailing wire the arm to the house floor.
