After a fantastic Morocco trip, I thought I'd just update all those interested in the technical issues that arose with the m3w's during the trip.
13 x m3w's attended Morocco.
Various levels of upgrades installed across the group.
10 x m3w's drove approximately 1850 miles each.
2 x m3w's drove approximately 3300 miles each.
1 x m3w drove approximately 2700 miles.
Total mileage covered of 28420 miles. (approximately)

So the 'failure' issues between Malaga start point and Malaga finish point (24050 miles covered by 13 m3w's ) were:
Car #1:
1/ Bad connector pin on fuel pump causing no fuel pump - rectified.
Car #2:
1/ Fuel pump failure (original part!) - replaced with Walbro at a coffee stop.
2/ Exhaust silencer weld failed at front pipe join (MMC exhaust) - exhaust removed at overnight hotel stop - local welder collected it (on his moped!) and returned with it fully repaired in 45 minutes!
Car #3:
1/ Rear wheel brake cylinder failure that led to hand brake over adjusting and therefore binding on drum. Removed back wheel in hotel car park early one morning - freed brakes by removing drum and isolated rear brake line. refitted and all good and continued on with tour albeit 30 mins later than scheduled start time.
2/ Very high front tyre wear rate - 80% wear on a new set of Metzeler's in about 1000 miles...just made a tape measure adjustment/guestimate to tracking and tyres and tyres lasted the remainder of the trip back to Malaga.
That was all.
The flatbed recovery truck that followed us in Morocco wasn't needed.

So I would say we can all agree that the m3w can be a reliable vehicle if maintained correctly with the required basic upgrades actioned..
