If you are considering that short and light weight of a camper, CoG and overall weight is of ZERO issue in a 3/4 ton truck or larger.
Don’t even entertain the fodder that you will inevitably hear in this thread about calculating weight etc.
You’ve done more than sufficient homework already to determine this is a more than suitable and safe setup.
Sounds like a great adventure rig if you can handle the ultra small space a camper that size affords.
And even if the CoG ends up behind center line of the rear axle, that is also of zero consequence considering the truck you’re planning to haul it with.
