Hi all. I have a 2010 LS challenger (manual) and we tow a 2014 17.56 2 OB with it. The vehicle has been fitted with OME shocks and heavier springs and has a tunit chip fitted. It also has drawers, a roof rack and awning (I only mention for reasons of weight and drag). We get around 8.5 to 9L/100km around town and we live in a hilly area. With the van loaded on we get somewhere between 12,5 and 14L/100km mostly depending on the amount of wind. Tend to tow around the 90-95 mark depending on traffic and other conditions. It's actually not much more than the camper trailer (1.25 ton) we upgraded from though I tended to sit on 100km/h.
I have found the vehicle to be very good at towing and keeping the fuel bill down. I compare this to friends with a slightly older expanda outback towed by a Landcruiser and we're less than half their fuel consumption.
You definitely know you're towing something but the vehicle will happily chug along at speed in fifth on the flat and it's unusual to have to change down as far as third for the steep bits. For those about to jump on me about towing in fifth, Mitsu says it's fine provided you are changing down when you hit the hills. They have inspected the gearbox after about 80,000Km of towing (50k camper, 30k expanda) and no issues so I ain't arguing with them.
I'm very happy with this setup and expect you'll be happy with your purchase too but as with any vehicle, they come off the floor for general use and you always need to consider what you'll be using the vehicle for and whether it needs some modification to do the job properly.
See you on the road!!
