It's a towing machine!
Posted: Mon Mar 31, 2008 7:45 pm
Okay, after much research, and asking questions, this is what I've learned and done to the Moon Machine:
-although not confirmed through documentation I've seen, these vans are reportedly able to tow 1700kg out of the box (no mods other than a hitch);
-while it's only an 85hs (83hp) diesel engine, coupled with the low-geared transmissions it should pull all day, if at an albeit slow speed on particularly steep grades (and it's not going to set any land speed records);
-and at a little less that 8 feet wide, these vans are narrow and so consideration should be given to the width of whatever is going to be towed (to minimize wind shearing, especially at highway speed).
We had one of these before we bought the van... ...so we had to get one of these (from E&H Hitch in Burnaby)... ...and then we wanted one of these... ...and due to weight, I wanted to put in one of these (to ease the load on the van)... ...and that's when things got interesting.
BC requires a trailer brake controller when the towed vehicle is more that 50% of the weight of the towing vehicle. Therefore, I was looking for something that weighed in around one tonne. I knew if I got something small enough, I wouldn't need a trailer brake controller, but I wanted one just to take some of the load off the van's brakes. We lucked out and the tent trailer pictured is only 545kg empty, and after we loaded it up for this past weekend, we checked on one of the scales and registered 802kg.
So, as can be seen, I mounted the controller on the side of the transmission box (I didn't want to put it under the dash because I have large feet and didn't want to be catching-up on it every time I got in and out of the driver's seat). The wiring runs forward to underneath the dash... ...this is the brake line going out to the rear of the vehicle (snakes along the underside of the vehicle, left side, past the fuel tanks), through a spare grommet I found near the middle of the floor pan... ...and these are the power lines going out through the floor pan near what I think is the speedometer cable (they snake their way up to the battery compartment... ...this is the brake sensor (the blue line), attached to the brake light line (the lower green line coming off the brass-colored cylinder, which is the brake switch) above the brake pedal... ...the brake line (blue) goes back to the 7-wire plug (the plug is grounded to the frame (white), and the trailer is grounded to the vehicle through the plug)... ...and all of that goes together to look like this: And finally, because the screw-down bolt for my spare tire was bent (discovered that when I was taking out the tire to run the brake line), I moved the whole thing up to the roof rack, like thus... How's the performance, you ask? Well, the Moon Machine wasn't setting any speed records before, but it did go a bit slower. We managed the Malahat though, and those of you who attended the meet at Rathtrevor Beach saw it all connected and running. On the way back to Victoria, the poorest speed uphill was between marker 20km and 16km on the Malahat (that's a tough hill regardless). Shifted out of overdrive, waited till it caught up again, and then back into overdrive (it down-shifted on it's own to second on that hill, but usually stayed in third). Still maintained 55km/h up that hill, and on the flat got it back up to 90-100km/h (I never go much over 100km/h anyway). Took a bit longer to get back up to warp speed, but still got there.
Trailer hop? None, but I don't know if that was due to the trailer having brand new tires, was heavy enough or whatever. Not sure what makes a trailer hop behind a vehicle, but it always freaks the s*** out of me when I'm behind someone who's trailer is bouncing around behind them. Know what I mean?
Fuel economy wasn't affected that much, maybe another half-kilometre less per litre (8.0 km/l instead of my usual 8.5km/l).
I probably wouldn't tow much larger of a trailer, but that's just me. As for great distances, I don't know how far I'd go. I guess I'll have to find out, maybe Alberta or beyond? Where the road takes me I guess.
