I am going with the same type build and was about to pull the trigger on the Yakima Overhaul HD. Did you go with the optional side rails? I am wondering if this will add extra support and allow you to add more weight.
I'm holding off on the side rails. I have both XL and L crossbars. For my trip to Rap Assault next week, I am camping on my way down and back and going with the L rails, tent and no basket or awning. Travel fast and 'light'. The XL bars allow me to add the annex to the bottom of the tent and have it hang straight(ish) down because of the rear fender flares and a room on the ARB awning and same thing. The L bars don't reach out far enough to do that. Plus I want room on the bars for my kayak sometimes. I digress.
I am holding off on the side rails for now. As you say, more weight but in terms of more stability, I don't think they would add much over having the tent on there. Maybe a bit, but more dead weight. Plus I grab stuff in the bed all the time, so am a little cool on the side rail idea. I haven't ruled them out.
