Good idea, thanks for the work put into this thread, really really well done.
Edit - wanted to link to possible RCI skid group buy this fall:
RCI Off Road Fall Group Buy 2017
I used the old thread 3 months ago and settled on Rocky Road Outfitters for Sliders - just got a shipment notification email 2 days ago from UPS Quantum View - still nothing from Rocky Road since the original order - no shipment notification, credit card billing confirmation, etc... Had totally forgotten about them since I ordered in June.
They do say some items are build to order but that's too long... I'll post when I get them put on, arriving next week, but even if they're perfect I wouldn't recommend due to customer service and wait time unless you're ok with at least 2-3 months wait and enjoy the surprise of a large credit card charge hitting randomly when they ship...
