The Northern Lite 10-2 EXCD SE should clear the cab fine.
Northern Lite recommends a rubber mat under their campers.
I think they even require it for warranty purposes.
You can use a hitch extension, but I don’t like them.
I prefer to stretch my trailer tongue to reach the truck.
Benefits are many. No extra heavy junk to attach and remove whenever you load/unload your camper, and superior towing physics, mainly.
The Northern Lite has nothing has nothing hanging down under the rear so there’s plenty of clearance. You’ll want to relocate the tongue jack further aft.
A set of Torklift Fastgun tiedowns make life a whole lot easier loading and unloading.
Apache Camping Center near me (Seattle area) told me they’d throw them in the deal with the camper, ask (beat up on) your dealer. They’re expensive.
They sell locks to go on the Fastguns, so no one makes off with them.
I have a set but really some tall-shackle padlocks would work too.
Your F450 may not need any suspension help. I’d try it out first before adding anything.
Torklift seems to be the go-to for the frame-mounted tiedown brackets.
I made my own, it’s not rocket surgery if you can weld.
Get a 7-pin RV type connector in the left front of your truck box and you should be good to go.
Be really careful of the right rear corner of your truck bed as you back under the 10-2, that’s the tightest spot.
