Having a couple of BB events under my belt, I'm squarely in the middle as far as ability as a driver and with the truck. I don't mind being on the same trail with more capable and less capable rugs.
I think what Wade had me and
@Capt Ron do on our first BB trail in our Crawlabago's was the smartest thing we could have done. We were on Hell's Revenge and he split us up and had us follow a more experienced/capable driver/truck. Basically not wanting both of us to make the same mistake possibly. One instruction was given though, we may not always want to take the same line as the more capable rugs in front of us. Wade called out the less extreme line for us as we got to them.
Here's the thing, I've done a lot of wheeling in my truck and know the limits better than anybody. But full on Moab slickrock I wasn't used to at all. So the pride side of me didn't want to have any restrictions to go play, but the realistic side of me understood I didn't want to be "that guy" and have a problem and ruin it for the rest of the group.
Stuff happens on the trail for sure but being able to limit the possibility for the sake of the group is needed. That can be swallowing a little bit of pride If you are new to Moab and letting the trail boss know if your experience is lacking or the truck doesn't have the same level of gear as the rest. At least knowing that the leader can make sure the lesser experienced guy can be put with a more experienced person to walk them through stuff.
Initial perceptions of people seeing my rug out on the trail is there's no way it can it can wheel like a K5 without the camper. Yes mine has a little different limitations due to the CG, but it can still do quite a bit. Wade even commented to me after my first one he was surprised how well we both did with the campers.
My feeling on the more capable guys/trucks is that they will want to do the tougher trails because it matches the ability they have. So the need for trail choices that fit the abilities of all are important. Which is where we all come in, speak up when the discussion comes up here for trail choices. I made a late decision to go this year but it was pretty obvious the trail choices for Saturday were over my ability or could tear the truck up. Mark and Wade made the suggestion if I wanted to do a tamer ride on Saturday pick one and I could lead it. I've lead my group of buddies on weeklong trips off road before so doing a day run didn't bother me at all. It was a very easy day on the trail, but we had a really wide span of trucks from Ron's crawler on giant swampers to a bone stock K5 with a camper on 31" tires. Most of us never shifted out of 2hi but the stock truck needed 4lo for a couple of the minor steep climbs we had to navigate. We all had a fun time saw some really epic sights and had a great day on the trail.
One other thing ties into this is communication. It would be great if everyone had the right radio to be able to stay in contact to make sure all are making the right turns but also letting folks up front know if there is a problem back in the pack somewhere. The ability to have the leader call out easier lines for the lesser experienced drivers could save time for sure.
Bottom line is BB is our event. Participate in the planning of trails, volunteer for trail leader/mid/tailgunner spots if you can. Get a radio so you can talk on the trail. If you are new, speak up. I've never been in any type of car/truck based event where everyone is so welcoming and helpful to the new guys.
). I get that it's hard to have that conversation if someone or some group needs to pick up the pace but I think setting expectations at the drivers meeting and FRIENDLY encouragement is likely the best thing we can do. Oh and sticking with minimum vehicle equipment requirements for specific HARDER trails
