I currently I have an 05' Toyota Tacoma with 38,000 miles on it. I bought it for gas milage purposes, but when I bought it I wasn't pulling anything. I now have a 22' pontoon boat with a 150hp motor on it. It's a pretty good load. I also live on a farm and have other trailers to pull as well. My Tacoma pulls the boat ok, but it jerks me around alot. My main question is should I buy a new duramax now which would be an 08', or wait to see if GM is going to change there body styles again in 09' or 10'?
