You got it. The body "boxes" the frame. Pickups have a lot of flex behind the cab. Most pickups are not overloaded so no problem. The worst load for breaking pickups are slide-in campers. Heavy service bodies often have expert mods to the frame.How so is the Suburban stronger than a pickup? Are you saying the frame is stronger? Or the body makes the frame stronger?
'Burbs have lower tow ratings, by a little, due to the body weight. As for actually pulling something, 'burb is same as pickup.
And, I'm not saying frames can't be modified. They can, but should be engineered. Welding on frames is specific to the application.
Start getting into 9 or 10k plus tag along and even 3/4 ton turns into a butt puckering, white knuckle ride. No fun.
The load matters. My 12k toy hauler has 1200 lb tongue and 12' 7" height. It pulls hard. A 10k car hauler is an easy pull comparatively.
Big loads on small trucks are downright dangerous on wet streets. My truck has a jake brake that can cause problems on slippery roads. Trailer brakes will skid on wet streets. Hi level contol boosters should be on lowest boost, or no boost on wet roads. You have to have the normal level electric brakes functioning.
8k plus and SRW trucks begin to get complicated. Most manufacturers are overstating their tow ratings. Ram 1/2 t for sure. Ford and their tiny turbo crap is another.
Most thinking people who drive something described as overloaded will sense that it's dangerous. Some few must find out the hard way.
BTW, 454 L29 was found in a few spec Suburban 800s in 2000. Some fleet owners didn't want 8.1s. Unsure why.
One of the friendliest tow engines (IMHO) and great for daily driver was the 6.0 with Allison or 4l80. Allison is slick.
Cheers.
