I put a Trailair pinbox on, It helped ALOT on the rear end bouncing up and down. Just added the tri-glide to help with the chucking, and have yet to go anywhere.
It is not cheap, but I would advise some sort of air hitch / air pin box.

Had airbags on our F350/Raptor combo and though I had them from the start. I didn't air up once and heading out of town I hit a spot that was bad on my previous setup and noticed it again without the air in, but when I was aired up it wasn't an issue at all. Just helps stabilize things and keep the truck level. Glad I had them.

Unless your hauling a cord of wood in the back of your truck I doubt if the weight back there makes that much difference by the time you get down that 39 feet to the garage...
I would suggest you weigh your truck empty by it's self, then loaded with all the wood and stuff in it then hooked up to the trailer both going loaded and coming home empty. This way you will know where you stand on weight...
If the bouncing on your truck is like Purposing kind of like going over rolling waves I think Air Bags would help. Throw on the airbags don't worry about a on board compressor. I ran the air lines out the rear by the license plate and air up with a portable air pump. You can play with the air pressure till you get the ride you like.
Air compressor has digital read out..

You can look into KYB Monomax shocks. They'll stiffen up the ride empty but loaded they provide great control of bouncing and wallowing.

If you are just off the overloads on the trip home, you could be bouncing off of those?
I have this issue when I am loaded in this sweet spot with 1/2" gap. I air up the bags a tad to open the gap a little and it smooths out.
If it is just a light valving issue with your OE shocks, the KYB Monomax's suggested above work great for the cost. If you are willing to spend a little more, the ProComp MX6's are adjustable mono tubes and work even better.

The airbags made a noticeable difference for us. The worst stretch we've been on is 880 through Oakland and they helped a lot. Also getting both truck an trailer level when hitched up and EZ-Flex on the trailer has made a world of difference.

The bags helped smooth out the ride on my '05 a LOT but that was because I was just barely touching the big overload spring and the bags got me off that and leveled the truck. The 2012 doesn't need them, trailer compresses the springs just enough to be level and it rides nicer than the '05 with the bags.

This (frame level) and the comment about bouncing on/off the overloads are real important issues to tackle first before any kind of band-aid like air bags or cushioned pinbox.
If trailer nose high the rear axle pounding won't go away -period.
Trailer shocks and or cushioned equalizers are a must with trailers IMO. Any trailer builder that says otherwise is ignoring the physics involved in how a suspension works.

Getting to where i'm camping, the rig drive great cause i have wieght (wood, water, ect) in the bed of the truck which equalizes the wieght. It is a different story when i come home because i dont have that wieght(wood, water ect) in the bed. Problem, when i hit big dips in our under funded CA highways, the rear axle of the truck bounces up and down "bad" because, of all the wieght is in the BACK of the TH and there lack of in the bed of TV. Question, would Airbags help lesson or eliminate the bouncing???
I would like to see a picture of how you fit all that in a 14' garage.
