Best place is directly under the axle
but, because the Hunter has a drop axle
, it might be necessary to drag the flat up onto a leveling block/ramp to get it high enough. Lacking that, use the frame, right behind the rear spring mount and leave the trailer attached to the tow rig.
I carry a can or "Spare tire" stuff that will take care of most small punctures, at least until you can get to a repair shop.
I also carry an RV endorsed AAA card so I don't really have to worry about where to lift the trailer.
Before starting out:
Be sure that your tires
are less than 6 years old, check the dates on the sidewall. There seem to be more problems with tires
that fail from age than from punctures (I think)
Be sure that they are inflated to or near maximum PSI shown on the sidewall.
The current land speed record for a towed trailer is 140 mph, you don't need to try to beat that..... Drive 55....
