What size trailer is needed to comfortably carry 3 sleds. The sleds are a 08 Nytro RTX, 13 Apex SE, and 96 VMAX4. All short tracks. I currently own an enclosed 2 place but would like to upgrade so I can carry all 3 so I have a spare sled if needed and also bring spare parts and anything else needed. Speaking of that, what do other guys carry in their trailers that would be wise to have that may get overlooked?
