Hi guys,
I wasn't sure why I needed one.
There have been a couple of occasions where it would have been handy, but not vital,
Judging by your op, I would guess you do not need a roof rack.
I tend to go by the guide that if you don't need it, don't get it. If you have never used it, don't keep taking it (first aid-kits, extinguishers and good judgment are exceptions).
Hanging around this forum can easily create an impression you NEED this, that and the other. That just isn't true. Your own varied experience and equipment (that's what it was before "kit" became the preferred term) will determine what you NEED. Lots of us here are romantics, image conscience, label collectors and fauxverlanders. We enjoy nature, travel and appreciate fine quality. We use those interests to justify continued gear purchases and vehicle mods. The large majority of us do not or cannot get out on the road as often as we want. Most of us spend our time planning for the too rare journey, dreaming of adventure and focus on building an overland vehicle. It's a harmless hobby and dovetails with hobbies of travel, exploration and adventure but should be seperated and isn't vital to one another.
Let your experience be your guide. It's really easy to go overboard with "must haves". Just accurately determine if it is a must have or a wanna have before shelling out the coin.
