I've weld frames in all three z/45/ and straight cuts and never had a problem with any of them I just prefer to use the z and if it's not possible to use a z I like a 45 and I only use a straight as a last option if room or the frame shape dose not make it possible I actually went and looked at a truck for the cab and it was a wrecker at one time and it was cut straight with no fish plates (which I don't recommend) the only extra support was piece3x3 1/4wall squad tube welded to the top rail for the wrecker bed to clear the step up in the frame it was a 89 crewcab that was a wrecker scene 91 and the truck was just parked about 5 years ago when the bed was put on a 4x4 truck with all that being said as long as you clean good and get good penetrating weld and plate the inside with a fish plate I don't ever see you haven a problem
