Just bought new 321 BTS total lenght 36 ft traded in 29 QBH which was 33 ft 6. First trip will be to Bristol for race on April 19 weekend. Trailer is awsome floor plan has everything that we wanted and didn't have in old one. Not sure how mich difference that extra lenght will make in towing looks like we have about additional 10 inches in tail swing vs old trailer. Not worried about truck have Dodge 3500 dually dsl. Bringing it home on April 4 so can get everything positioned before trip short trips after that until summer when wife gets done with work then headed to Yellowstone. Looks like great trailer can't wait.
