Depends on what you need. Toyota probably makes the best small truck. Ram with a Cummins is probably the longest lasting truck engine. The 5.9 Cummins before 2007 won't have to have that blue def stuff and be better fuel mileage. Thing is, how long are we going to be able to get fossil fuel to run them? Or be able to afford it? The 5.9 Cummins can at least run on cooking oil. As long as you can get parts the Toyota or a 3/4 ton truck will run indefinitely. If you drive a lot then diesel could be a good solution. Diesel usually gets about 50% better fuel economy and the service intervals are farther apart. Diesel repairs are more expensive. Most diesels also need to be plugged in to keep motor warm in cold weather for them to start well in the morning. My Cummins has never had that problem. However to date the coldest weather has only been 9 degrees since I bought it. Also if you're out on the road diesel can be harder to find than gas
