Howdy,

zip ties.
Hooked up and ready for the road... ensure the hand brakes are fully off. Check the lights, brake lights, turn signals
check the tires, if they are run flats (17 psi painted above them) then a good towing air pressure is 20 psi
go down the road. Before getting back on the highway, about 2 miles, check out your stuff again. , so place your hand on the axles and hubs. Do this all again after say 10 highway miles. It is easier to correct a tight castle nut early, than to have bearings burned up farther on the trip. The MEP generator sets on trailers follow along nicely.
I only say this because you are driving some distance.
Yes, the Letter-Kenny guys are great to deal with. The site is off base. They make use of a large surplus loader, and bring your unit out and set it right down where you want it.
