Hitch racks, hide lights and tags, be carefull. I have moved a bigblock over 200miles behind a Suzuki on a kit trailer like you say. No troubles, make sure you keep the bearings lubed.
Sounds like you are following the sameness between rv and boats. Good, look for solutions to your ventilation there as well. There are many possabiltys. That only use a 3 or 4 in hole. Keep up the good work.
