Frame strength of small TT's

I have read on here about frames welds cracking and axles bending. Are these problems basically with longer heavier TT's driven on bad roads or is this prevalent with short TT's, 18-22ft 3500 lbs or less UW also? I can't find any info on frame thickness or material on MFG web sites. I would think that the frame thickness would be the same on a 22 ft vs a 27 ft TT, making the frames stronger on shorter TT's, but that is just a guess. Also I see where Winnebago uses huck bolts instead of welds to attach frame structures together is this process better than welds?

    I am on my third travel trailer - a 19 footer, a 25 footer and now a 37 footer. All the frames were welded and I never have had a problem

    The 37 footer is in a permanent spot and I snow bird in it. I wouldn't tow it for all the tea in China ! It has about a 16 foot over hang behind the rear axel and I cringe every time I think of it being overloaded in that area- going down the interstate at 60 or 65 and hitting a bump.
    I have never heard of the frame cracking, but then may be people don't publish it when and if it happens.

    In the case of my old 24 foot trailer, yes the shorter trailer shares the same frame rails as some of the the longer models. To a point. I believe that makes my trailer stronger foot for foot.
