Just a heads up with respect to the trailer project.
My opinion,as I attempt to complete the project,is that nobody should undertake such a project unless they have a 20-foot by 35-foot flat.level slab,and 6 castored tire dollies to put the tow vehicle and trailer on.
I'm losing 2-days work in about 2-seconds negotiating my un-level driveway and local community roads.
A 'proper ' shop would allow a check of full range of motion without ever leaving the shop.
You'd be amazed what a 150-hp engine,in first gear can do to steel.
