Aloha, not many places one can travel to on and island.Stickering up your vehicle just for the look seems silly. If you don't have an idea what decals you want to put on it already, then maybe you just don't put any on?
Any decals I've applied have been from places I've been, products I use, or something I like and have a story about if someone asks.
Asking other people for their opinions on your personal decision to decorate your truck strikes me as an odd question. I'm not a fan of plastering my truck with stickers, but that's just my taste. Each to his own. I have four stickers on my truck, each with a special meaning to me:
I think any car plastered with manufacturer's logos looks like shit. Even race cars that are covered in logos. I don't care what oil you use, I can see you have aftermarket accessories bolted on - I don't need a sticker to tell me that. That crap looks like a rolling billboard. The only extensive stickering I find halfway interesting is when people put the flags of the countries they've driven through on their vehicles. That tells a more meaningful story than what products you want to advertise. Do whatever you want. It's your truck.
- a ZA white oval nationality sticker because I used to live in South Africa.
- a small sticker in my rear quarter window from the Land Rover Owners Club of KwaZulu Natal, South Africa, because I am a current member.
- a Sani Pass sitcker because I've driven up it a few times and had some good adventures in Lesotho.
- a Union flag because I am a British citizen. (Fun fact - it's only called the Union Jack when it's flown at sea)
