88 xj, 4 door I6 4.0L 4WD
Travel Trailer is 1950 pounds, single axle. No tanks in it, one battery.
I cant understand L/100km so I use km per ltier.
I got 4.5 km per liter (10.5MPG) on a full tank 70 liters, towing a 10 foot travel trailer around in the city.
I then got 6 km per liter (14.1MPG) just filling up 10 liters at a time towing trailer around in the city.
Not heavy on the gas at all.
I worked out the math and think if I was not towing I would get around 8 to 10 km per liter (21.2MPG=9km/L) on that XJ. (I will test this theory out when I do my first un-hook either at Walmart. Or powered campsite to do some XJ and trailer repairs)
From this I gather if i bought a cheap truck ($500 - $1000) left the trailer hooked to that and let sit for however long the city bylaw books allow and used the xj to roam about, in a year it would save me $, not to mention all the rent and utility money I would pocket.
I could use campsite, but thats $.
Could camp out in the bush, but thats more gas $ to and from.
