Hal,

Now I'm going to demonstrate how pedantic I am.

I have been participating in this forum for 10 years and can't remember ever reading about a frame that failed because it was light
weight.

I use the email system and have folders for particular systems I checked my Frame folder and found stuff about rust damaged frames
but nothing about frames that bent from bring too weak.

Yep, Dan Stuckey's replacement frames are "beefier" as were the frames Clarence Buskirk used for his 29 foot stretches.

The GMC was designed by a team of professional automotive engineers, each with specialties, they "ran the numbers" and designed a
frame that met the requirements of the vehicle. I wonder if anyone that frequents this forum has the capabilities to do the same.

In my mind we're "tinkerers" (at least I am) with varying skill levels, I've seen your GMC and it is awesome.
