Well if you want to talk % of life wheeling, the 1st time I took Co-Pilot out he was a scant 2 mos. old. He drove a 4x4 for the 1st time alone when he was 4 yrs. old. He is now 12 so if you have been wheeling for less than 12 yrs. he has you beat. 12 yrs wheeling and 8yrs. in the hot seat. If this question is asked of him his reply is "I was born with a crawler knob in my hand", and crawl out he did I think it was a 26 hr. labor.
