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.
