Can you guys give me the LOW DOWN between the GM/Chevy PU & Dodge

It isnt what is in your list, but i have a 94 ram 2500 i bought last year. Its a beater. But it seems like a good truck. Every time i fiddle with it i like it a little more.
Turns out the “head gasket” leak is the heater hose o-ring.
I got it for 900,will likely need a grand to make it pass safety.
I have had old chevys and still use my 80 power wagon in the summer. I have owned it for 25 plus years.
I cant say either is better or worse, but parts cost is usually cheaper for the gm’s. And likely more parts available at a moments notice.
