Interesting that the listed curb weight for this truck is 4288 lbs, when compared to my Srt8 jeep, its a lightweight, the Jeep listed curb weight is 4788 and as tested by Edmunds was 4819lbs.
Cast iron big block, and solid axles still don't make up for all weight of the safety equipment and luxury options in the jeep.

Chrysler didn't know what aluminium was in 1978 and apparently still doesn't.
