I don't think that truck is so bad and it seems about right for the money? The C7 in a tandem wouldn't be my ideal choice. I don't have a problem with the length, it would be very maneuverable. I would like a heavier front.
First place I worked had a Pete quad that was 300 horse with a 8LL and it seemed fine but realize that was a few years ago now...
Do or do not. There is no try. yoda
