Suspension Bolt Not Flush--Cause for Concern?
While doing my pre-departure tire inspection I noticed one of the spring hanger bolt nuts isn't flush with the frame. It is hand-tight (nothing obviously loose) but the gap made me question if something is going wrong under the trailer.
Thoughts?

That is acceptable and normal. The nut butts up against the shoulder of the bolt. That allows the shackle to pivot as needed. The gap on Lippert suspensions is even larger.
You can see the very large gap on my former Lippert suspension in the picture below:

May I suggest that you get a grease gun and push some grease in the wet bolts. It looks like you have the typical red grease wiped on the zerk fittings and no grease actually pushed through the bolts.
I would bet when you push black grease through the zerk fittings there will be no red grease come out.

Jerry is absolutely correct. We've noted this condition several times with GDRV management. They promise the bolts are being properly lubricated, but anecdotal evidence proves otherwise.

While the gap is normal (as stated above) just to feel good about it I would still put a wrench on it and Make sure it is tight.

While this is "normal" for towable RVs and probably other trailers as well, the frustrating thing is that you would not see this situation on any other means of transportation from bicycles, to trucks, to trains and planes.
A lot of the noises that we hear from the trailer suspension, particularly when backing and turning . . . are the springs sliding back and forth on the bolts between the shackles or the clevis brackets. Not much we can do about this without custom machined parts.
