I say a half ton F-150 will pull a 4200# trailer with ease. I pulled my 21' with a half ton subsuban and it did a fine job, the new F-150 is a beast.... I wouldn't look at a mini truck, but for that trailer the F-150 would be fine. Hunter http://members.aol.com/hhamp5246/roadtrip2005.htm Alternate email: hunterhampton@gmail.com
