I own a 2010 tundra. I had the option for a new vigo and this tundra and i bought the tundra with the eyes closed.
1- fuel consumption is 5.5 km/l if driven with a light foot
2- maintenance is CHEAP!! oil change costs 7k,oil filter costs 3-4k,air filter costs 2-3k,brake pads front 7k,back 5k. plugs costs 10-12k for a set of 8. etc etc
If you are a good driver then you would learn to drive the LHD in a few weeks,though getting parking in tight spaces is deff an issue,but i usually jump on the big footh paths if i dont get space 
If you get into an accident,parts like lights,bumpers,side mirrors would be an issue to source,which are mostly found in dubai.
Other then that its a wonderfull truck!
