I am using a 14 FT single, I can get 2 ZTRS on it but for some of my jobs I need to take 3 mowers. What are the draw backs to a 20 FT tandem and should I try and stick with a 14 FT ? How much more fuel will the bigger tralier eat. I have a 3/4 ford diesel van so it can pull it. Your thought's from people who have gone bigger on a trailer. I try and be as efficient as possilble, I just do not want to end up with something to where I should have tried to use the 14 and just use less equipment! Thanks.
