I have been thinking of how I might mount my over-sized spare on my brat, and I saw a truck the other day with the spare right on top of the roll bar, wondering if anyone else has tried this? I am afraid it would get caught on branches and such too much. Any comments?

I dont have a roll bar in mine so I put my big ol spare in the right front corner of the bed standing upright... I use a bungee cord through the wheel holes to tie it to a tie down loop up there on the side of the bed.

well unless you have a brat thats going through drainge tunnels under the roads i wouldnt worry. most trails are well established (read full size truck use it). my biggest worry would be them either getting in the way of the t-tops or angle it down and in the way of the back seats/bed area. think id bolt it in the bed like the prerunner baja racers angeld and by the tailgate. OR BETTER YET put it on a low pedastile type base and let the back seat passengers use it for a table when your at sonic :-p
