Ok guys need some advice and opinions here. Building a sled deck out of old aluminum 2 place trailer. My questions are what length do i make the actual deck? I would like it to be able to fit a 6 or 8 foot bed. I also plan on adding 1 foot dove tail to help with loading. My main concern is if using a truck with a 6 foot bed would i have issues if wanted to pull trailer as well? Thanks in advance guys.
