Well didnt know this section was here but i have 2 suburbans one ive had for about 8 months now its a 84 k10 with a 6.2/700r4 trans setup and i like the mpg i get with it and have had some fun with it offroad till the trans went out in it. and about 3 weeks ago i got me a 89 R2500 that has a 350/sm465 setup in it. im still learning the ropes for it with driving stick but it has 3.43 rear gears and its my first vehicle with a stick shift. it use to be a ncdot vehicle we think for land survey but thats unknown since it didnt have any documentation from the P.O but its still a nice vehicle. its also the cleanest square rust wise ive seen that not been restored having about a 1.5inch section at the rear wheel well. Here are the pics of my two beast that get better mpg than the dually i had
