Well I own a landscape business and I want an isuzu diesel cabover to haul my equipment around. My truck isn't reliable any more to depend on every day to pull my trailer. I want an isuzu for about 5-7k. I should be able to find one w/ a little over 100k for that price. What do I need to look for on the isuzu diesels? What kind of fuel mileage to they get? Do they have any weakness like the lift pump on the 24v?
