Just starting my build here. Need to get a tent and awning. Looking at OVS Nomadic 3, Annex and OVS Nomadic 270 Awning.
Was going to go low with the tent, but am going higher so I can fit under the tent and have the option to use the annex for more space out of the rain (since I'm on the west coast). And awning for rain too (or shade when I am lucky enough).
Went with Retrax Pro XR retractable. Need to be able to open it all the way once in a while, or would have gone with the Diamondback. Those just look great (and are more secure too). Adapters for Overhaul HD rack, the rack and the wider HD bars. Want room for tent and other stuff on the rack sometimes like kayak or Yakima skinny warrior basket. The wider bars also help the annex clear the rear bulging quarter panel.
The racks adjust 19 - 30"
Looking at adding a platform (low profile) on the cab. Not for anything particularly heavy, but could come in handy. Will see, not sure about that. Don't want the extra noise or when the RTT is off, the extra wind resistance.
The way it sits, now, should be able to have the RTT base a few inches below the roofline to reduce drag a bit and cheat it down for a lower centre of gravity, while still being able to walk under it. Will need to fine tune it based on sag with a normal camping load out of gear and water etc.
The shadow makes the tonneau look tilted or weird.
