Look through this thread for ideas:

If that camping trailer is your main thing towed, consider removing the hitch and using the bumper itself. If it is OEM or equivalent, it is at least a 3000 lb tow rating. IIRC, you could get bumpers with 5K and maybe even 10K tow rating. Back before the Feds started mandating bumper designs. Since most folks have hitches now, NOT having one would be different.
If you camp a lot, lowering may not be a good option. Or if your roads are like a lot of them around here.
While I don't like the idea of changing paint that seems in good shape, maybe changing the gray to a color that pops a bit more.
Maybe a semi-decorative headache rack. Just in case the bicycles get loose.
