Uncle had a truck, I dont remember what brand or what year. But I do remember him climbing into the engine bay and sitting on the front tire well to work on the engine, because I was on the other tire well watching him. and we both had absolutely loads of room to move around. more so me, being a kid, but he was a big man and he still could slither around everywhere in that engine bay to get at what needed got at.

vehicles, especially trucks, used to have an insane amount of space under the hood for working on the engine.
