...Hilux, both D-Cab? I would appricaite some advice on these two trucks? Are the single cabs any good or is it far benificial to have a double cab?
Many thanks for this!

Double cab all the way.Single cabs are fine, but if you want to store gear you will need a locking truck box in the bed. Mitsu or toyota.....tough choice. Both are designed rather well. I had a toyota extended cab that I ran up to 450,000 miles with only one engine rebuild. I have an eagle talon TSi AWD turbo,i.e. mitsubishi that has 250,000 miles on it and it runs swell. Both vehicle makes run forever if you change the oil every 3000 miles. I also had a mitsu mighty max 4cyl pickup that I ran to 300,000 miles with no rebuild at all. Both are excellent choices.

I would definetly go with the Mitsubishi...but I am kinda biased as i have a mitsu lancer. I have had REALLY great service. The only issue you might run into is with mechanics. I live in Michigan and i drive 30 miles to my dealership because 1) i dont trust other mechanics with my baby 2) someone just dont know how to work on them. If you are looking for a NEW truck Mitsu just came out with a new truck the Raider. Check out the link below.
