Yeah, left front is the normal plug spot.
You will need a 7-pin RV connector wired to the standard pattern (google it) but Lance their own pattern.
There are clamp-on tiedowns called Brophys that you can use that go over your bed rails.
Everyone used to use them, I did for many years. They just clamp on, you tighten them with one bolt each.
The frame mounted tie downs are better but I never had an issue with the clamp on brackets. Those might not be the ideal permanent solution but they’ll work to get the thing home.
And yeah, make sure either the camper already has “dually swing out brackets” on the front jacks or buy and bring a set. You need to be able to swing the front jacks out wider while loading onto a dually.
Bring a sheet of 4x8 2” thick rigid foam insulation, or some 2x4s or 2x6s to shim the camper up a little higher in your truck bed. You never know if the cabover part is going to clear your truck cab with a comfortable amount of clearance. Trucks and campers flex, you need a little space.
