Whenever we take a group trip we split fuel costs only, we take turns on the rigs and we all understand mechanical issues are the owners gig. Out of the thousands of miles put on a rig a year how can one figure out that, that particular trip caused the tire to blow, fuel pump to go out, battery to die etc. As the rig owner it is simply a risk you take. As for buddies steppping up to the plate, they did for me. We have an annual Jet boat trip over to the snake river every year. This last year the week before the trip I lost one of my axles on my Jet boat trailer and ended up scrambling the entire week getting a new one built and put under the trailer. Without asking or expecting anything my buddies gave me some doe to cover the costs. It was greatly appreciated and reminded me why these guys have been my friends for the last 19 years.
