A removable and raisable roof attached to four upright supports is mounted on an open bed trailer. Two supports are located on the left and right corners of the forward edge of the trailer; the other two supports are similarly located at the rear corners of the trailer. No side supports are necessary. Using elevating means within the supports, which can operate independently or in tandem, the front and/or rear portions of the roof can be raised and lowered separately. Using external attachable fixtures and ground mounted supports, each of the roof supports can be lifted from their mounted position on the trailer bed and the trailer driven out from under the supports and roof assembly, converting a covered van to a fully open van. If a fully enclosed trailer is desired, then tarpaulin, or other readily removable wall materials can be suspended from the roof and attached to the trailer bed.
