i have the 60/40 split bench in the truggy. ive sat in it 3 a breast and it sucked, nearly bumped my son in the face, chest or nutz everytime i wanted to shift the crawl box or hit reverse quick. i imagine a rear facing baby seat would be really cramped. also the drivers side bench section cant move forward very far without hitting the rear Tcase lever, which i had to bent the heck out of for the same reasons...
dustin found a poly bench seat with a cover for pretty cheap to put isaac in, i think hes about your sons age age? i wont take my new son on the trail until hes at least 2 and has fully developed muscles in his neck to support his head. ill cut the back out of the 'cab' and put a bench in the rear that can safely mount a baby seat, like a jeep fold and tumble, or ill chain/strap down the base portion of the baby seat...
