I used Google Image search and selected "Large". I found this one and it is huge - 5557 x 931.
Have you considered using a LAND ROVER logo, switching the letters around and having OVERLANDER instead? This is on my To Do list, but I was going to buy a couple of chrome stick on emblems from eBay.
I also thought about HIGHERLANDER but my truck is not yet lifted, so maybe neither is appropriate yet.
