You are caught in the age old "half ton" quagmire thinking they are all the same
Mainly because of using marketing nomenclature. Better to use actual references...like their GVWR & RGAWR
That 95 GM 1500HD is a unicorn that is more 3/4 ton...and with extended cab +long bed...is several feet longer than the others, which is a key stability factor, but not the only
What comes with bigger GVWR/RGAWR are BIGGER brakes, transmission, etc
Why it towed the same trailer better than the others
Look for 6k or higher RGAWR & +8k GVWR and longer wheel base
Get it that you don't mind older and note that that these higher GVWR & RGAWR TVs has more margin. Therefore should have more left in them...unless previous beat the snoot out of them
Oh...also note that a 95 +8K GVWR (3/4ton) 6K RGAWR is the SAME axle as the 1 ton dually of that era. Diff are in the spring pack & rear brake shoe with/wheel cylinder borel
