Ok folks i am looking into purchasing a full-size Blazer or perhaps a Tahoe so we are talking somewhere in the mid to late 90s depending on what i can get and what i decide to spend. Anyhow I am kind of partial to the 6.5 Liter Diesel engine because i plan to be towing around 5k lbs at times. I have seen a few 2 doors with the diesels but no 4 doors. Were these only available in 2 door and suburban trim but not 4 door? Also is anyone familiar with whether or not the 350 is a better engine over all or am i probably doing the right thing by going diesel?
