Lark 7x16 Enclosed Gray. Customers that invest in a Lark United Cargo Trailer are pleased to find that there is a 1 year warranty backing their trailer and that we are able to deliver the trailer they need to do the job. Sometimes that means a standard option trailer and other times, it means that we need to customize your trailer to really get the job done. We offer enclosed cargo trailers from 5 foot wide to 8.5 foot wide and everything in between. We encourage you to get a quote from a dealer near you before you make your trailer purchase decision. You'll be glad you did. PRICES ARE SUBJECT TO CHANGE WITHOUT NOTICE.
