we've done marsalling for a couple of punch challenge events with the RT, great fun to watch, I've took part in a few punch events with N44 too, the club events are less competative (well, to most of us anyway

) and the handicap system levels the field a bit. The extreme events, rock crawlers, or the winch challenge events are the hardcore events, lots invested in the truck to be competative, quite expensive to compete too.
It depends what you want out of it really, I reckon most of us don't even attempt half the punches, lots of folks in their regular drive, it's just a good laugh, and it's a bit better than plodding round the same old P&P sites. I imagine it's similar to plodding round Lincomb, but with a mission, and a bit of friendly competition the passengers can join in with.
There is an element of "stupid" on all the P&P sites, their aim seem to be to buy a sub £500 disco/paj and drive it into the ground, mindset seems common amongst our east european friends.
Trying to do all these club events with one motor you also use as a road vehicle is not really practical, too much spanner time with pressure to get the truck back on the road. I wanted something more reliable for daily drive and laning/overland (hence the 80) but I also want a trailer toy to join in with the club events, my current LR90 is way too good to be thrashing round P&Ps tho, I'm aiming to sell that (try and got some of my dosh back!) and get something much cheaper to thrash about in the mud, it's not about the mud per se (I prefer non muddy quarry site tbh) it's the camaraderie when we're all in it together, not to mention building the old driving skillset up a tadge.
