Tom -- great idea with the bracing under the shelves. I was going to look at it this weekend to see what we could do, but armed with this I think I'll grab my brads and some firing strips...
Avolnek -- I think it pulls better than my old Springdale that was nearly 1K lighter. I notice the weight going up hill on the highway but the truck didn't loose speed (though we didn't gain any either
). On flat terrain she's rolls at 65 like a champ. However coming home we did have one issue. Tried to flip on the truck's A/C and it was blowing hot air. Checked the gauges and everything was all green... However a heavy merge caught my attention and I left it blowing hot air for a min while I made sure to avoid any Darwin Award Nominees and "Clunk" ... "Hiss". I pulled to the side of the road and did a visual inspection. No tires blown, no engine parts displaced, no trial of fluids. I think I blew my A/C compressor though. I'm taking my truck to the mechanic this Fri to get it checked out. Here's hoping this is something simple and relatively inexpensive. But I have a bad feeling it won't be either.
That said, I don't believe this is in anyway connected to the drivetrain. Nor do I believe it to be a result of towing other than perhaps a little higher than normal engine temp.
Wrapping up this trailer is half ton towable IMHO assuming you have a big 8, your reasonable about how much weight you load into the truck and trailer, and you don't live in the Appellations. (I'm amazed at how quickly 9300lbs of capacity goes away with a 7600lb trailer, 600lbs of flesh and bone, housewares, and a few days worth of wood.
