IF your seriously planning a trailer all seems mute-$500ish for a temp solution to a problem that will go away?
Sell the TorkLift hitch & stinger, wont' need it, (well you might want the hitch) applied to money saved not addressing current setup, added to sell/trade the camper.
Otherwise front hitch/spare carrier, front hitch comes in handy, even if spare goes back under.
Other temporary options: back seat, inside camper, in the boat, in bed when camper off, or run largest tire that will fit-use as front spare-moving front to rear if rear flat.
Cant imagine being happy removing sway bar but easy enough to unbolt, crank up the shocks. Just briefly looked cause I couldn't see how interfering (Ford is in front of axle)
