I'm still battling between the new rack, RSI, GFC and Alu-cabin. really it comes down to is any one twice as good as the other? $1.8k for a rack, $3.6k for a RSI, $7k for a GFC and $14k for the Alu-cabin (when available)
I loved my rack until Wyoming taught me a few new lessons plus I'm in my 50s and feel the need to cover stuff.
RSI is releasing (or has released) the EVOa for our trucks. = cover stuff and reduce dust.. but I still need to get to my tent and since CVT is not very customer service focused, I'll be buying a hardtop tent with that. ~ another $4k.
Which puts me in the GFC category. While it's not likely that they'll eliminate dust intrusion, I would be able to step up into my tent from the bed. There isn't much in the way of storage and mounting capabilities, though and getting up to my truck bed is a challenge even at 6'6"
Enter the Alu-Cabin. More space, storage, support, ease of access, dust protection, weight and $$$$. I could set the alucab to have everything attached how I want it and attach/detach as needed.
Now, if I knew whether or not I would be long term happy with the F150 Tremor, I could plan/purchase accordingly.
