This is a nice rig, it looks good and is very powerful. The interior is roomy and comfortable for long trips. I pulled a 73 Cougar in my trailer with it and got only 6 MPG, but hey, it's a truck, don't expect Prius gas mileage. This is the best truck out there and there is nothing I would change about it, except I wish I got leather in mine.
I have recently purchased a good used 2007 Chevy Silverado 2500HD Crew Cab, long bed truck with 33,000 original miles on it. I have only had it for about a month now but so far it appears to be everything that I am going to need in a truck. It has the 6.0L Vortec engine in it so it should handle the 23' 5th wheel that we are purchasing as well, pretty easily. The truck runs fine, rides pretty smooth (for a truck) and handles fine. I'm getting about what I would expect a truck of this size to get on mpg, averaging 12.6 on the first 4 tanks of gas. I expect lower once we start pulling the 5th wheel.
I purchased this vehicle to tow a travel trailer which it did very well in the beginning. I dont have a lot of room so I'm going to list the parts that have been replaced on my truck at 50,000 miles.Front Locking Hubs,Pressure Relief valve,Rear end,Complete Engine with turbo,Turbo,Front axle, I paid $38000 for this truck and am now over $13000 deep in repairs the warranty would not cover the engine they said I drove through to deep of water and it sucked it into the intake from the bottom,bad investment on my part I guess these 4x4's arent supposed to leave the pavement.
Bought new to tow 5th wheel. 6.0 liter gas engine/auto tranny/cloth interior. Getting 14mpg around town (speeds range from 60mph to 30 mph, stop and go) Have not had an unladen trip on the highway yet so I don't know the mileage there but will by the end of July - I'm hoping for 18mpg. Paint is thin and scratches very easily - a big disappointment for me. Interior is dated; exterior is boxy, reliability has been good but I only have 6k on the the beast. Build quality is average. Ride is stiff even at 50psi in the tires. It does have power! Lookout boys, it's gonna unwind!
What an amazing truck. I have had it for a little over a month and put almost 3200 miles on it. New Duramax is incredible. Very little turbo lag. Everything about this truck is the way a truck should be. All the toys and finally a power rear slider integrated trailer brake rear parking assist. Navigation is easy to use and ride is actually improved
