    yep, especially in Minnesota. Not much you can do but cut out the bad metal and weld some good stuff in (plus add the braces that I believe B&B came up with). that'll keep the control arm mounts from bending.

    Lots of guys on here use fluid film to coat the frames so they won't rust.

    I have a small rot hole followed by a crack
    Going to weld it up within the next few weeks.

    Make sure you cut out the rust and a bit beyond so you have good steel to weld to. The frame accumulates salt and dirt through the factory holes. The old 93 1500 I had did that. When we cut it out there was about 5 lbs of crap in each side.
    Now when I wash my truck, I put the nozzle right in those holes and flush that crap out.

    and if you have a 1" hole from the inside out plan on it being 3-4x bigger on the inside as most of the boxed frames i have seen rust bad from inside out.

    and check local/ state inspection / safty laws for fixing / welding / repairing on a frame .

    in new york state your not to weld / cut / fishplate with in 6" of suspension mounting point last i recall seeing in the rules book.

    and seen lots of 88-98 style go bad begind cab were cab mount / box first mount combo is welded to frame . colects crap and thins out there also.
