mach1 Posted April 17, 2016 Share Posted April 17, 2016 I currently own a 93 Prostar 190 and am looking for a tow vehicle. One of my options is 2012 GMC Sierra with the 4.8L V8 and 3.42 axle ratio. Do you guys think this will be up to the task or will I regret not getting something with more power. It is a standard cab/regular bed with 4x4 and according to the manual should have a 6,000 lb towing capacity. What do you guys think? Thanks in advance!

Baller evolski Posted April 17, 2016 Baller Share Posted April 17, 2016 I currently own a 89 Malibu (similar size/weight to yours, and I tow it with an Isuzu Axiom, v 6. No problem (towing capacity 4,000). The important item is were are you towing it to and what type of ramp, if very steep, or slippy, 4 wheel drive helps.

Baller oldjeep Posted April 17, 2016 Baller Share Posted April 17, 2016 That boat on the trailer weighs what, 3500 lbs? You could tow it with a 4 cyl car, a half ton pickup will be fine. Link to comment Share on other sites More sharing options...
Baller Bill22 Posted April 17, 2016 Baller Share Posted April 17, 2016 I have a 4.7L in my Tundra and it pulls my Malibu just fine. Link to comment Share on other sites More sharing options...
mach1 Posted April 17, 2016 Author Share Posted April 17, 2016 Thanks for the input! It sounds like the the 4.8 will fit the bill. @oldjeep I agree that a four cylinder could pull it; however, that doesn't mean it should. I have to tow it the river every time I ski and would like at least some peace of mind on the road. Link to comment Share on other sites More sharing options...
Baller Craig Posted April 17, 2016 Baller Share Posted April 17, 2016 I towed a 94 MC Prostar 190 with that exact setup. Launched on a pretty steep dirt ramp for two years with zero problems. Towed very easily down the highway. Normal fuel efficiency was about 15 mpg, towing it was about 10-11 mpg. Link to comment Share on other sites More sharing options...
mach1 Posted April 17, 2016 Author Share Posted April 17, 2016 @Craig thanks for the input! Does yours have the 4-speed transmission too? Link to comment Share on other sites More sharing options...
Baller Craig Posted April 18, 2016 Baller Share Posted April 18, 2016 @mach1 I'm not certain and I don't own the truck anymore. It was a factory tow package, whatever transmission comes with that. Mine had a tow/haul button. When you kicked it on it would reduce the number of gear shifts as an attempt to reduce wear on the transmission.

Baller keithh2oskier Posted April 18, 2016 Baller Share Posted April 18, 2016 I have a Dodge Ram with a 4.7 and it tows my Nautique 196 no problem. I mostly tow all flat but the onramp after leaving the lake is fairly steep and blind so I do have to get on it pretty good but no real issue. I do notice my transmission will search for gears more than I like. I do have a tow/haul button but I really dont use it that often. But I do watch my tranny temp and its never been an issue even on hot (100+) summer days. Link to comment Share on other sites More sharing options...
Baller JAG Posted April 18, 2016 Baller Share Posted April 18, 2016 I think it depends on how far you're towing. My '96 Silverado with a 350 Vortec was a beast. It developed peak torque at 2200 rpm, so going down the road at 75mph was right in it's sweet spot. My current '07 Silverado with a 5.3LV8 has more peak horsepower (305 vs. 250), but the torque curve is moved up a bit and you can feel it when towing. It still pulls my MB Sports fine at 75mph but I've learned over the years that torque is what you want for towing, not horsepower. As the saying goes, "Horsepower sells, but torque is really what puts the smile on your face". :smile: Link to comment Share on other sites More sharing options...
Baller keithh2oskier Posted April 18, 2016 Baller Share Posted April 18, 2016 @rpg is right. This is where my Ram struggles with the smaller motor. Peak torque is almost at 4k RPMs where cruising at 65 if closer to 2k. Link to comment Share on other sites More sharing options...
Baller_ MISkier Posted April 18, 2016 Baller_ Share Posted April 18, 2016 +1 for @rpg. My 96 Tahoe with the 350 feels stronger than my 2001 Suburban with the 5.3. The worst slalom equipment I own is between my ears. Link to comment Share on other sites More sharing options...
Baller andjules Posted April 18, 2016 Baller Share Posted April 18, 2016 If you follow this thinking ad absurdum, there will always be a "better" vehicle with a higher-torquing engine with just the right torque curve, and an owner that takes pride in the fact that he "can't even feel" whatever load he's towing. Not being able to feel a 3500lb boat/trailer is not the goal, even if it does feel impressive. Find a vehicle that provides the best balance (price, fuel efficiency, utility when not towing), including handling the load safely when driving responsibly, which—with a 6,000lb towing capacity—the Sierra is (way!) more than capable of. It's not a tractor pull championship. It's a safe, unremarkable drive to the ramp and back. Link to comment Share on other sites More sharing options...
Baller brody Posted April 18, 2016 Baller Share Posted April 18, 2016 I have a 04 Sierra with a 4.8l and a 01 response Lx. Bought the boat 8 hrs from my house towed no problem even up to 75 mph. You will have no problems with this truck. Link to comment Share on other sites More sharing options...
Baller brody Posted April 18, 2016 Baller Share Posted April 18, 2016 I also picked up a nautique 200 for a friend and towed it home 24 hr drive. Did it straight thru again no issues Link to comment Share on other sites More sharing options...
mach1 Posted April 18, 2016 Author Share Posted April 18, 2016 Thanks again for all the advice! There are multiple places I can ski ranging between 10 to 50 miles away (so a worse case scenario would be 100 miles per weekend during a six month season). Luckily it's all relatively flat with not too many large hills. My biggest concern is probably the 4 speed trans. I'm worried about constantly feeling under powered or spinning a ton or rpms. I'm pretty sure it has a max torque of 305 ft-lb @ 4600 rpm. Does the 4.8 still stack up well with this kind of commute to the water? Link to comment Share on other sites More sharing options...
Baller oldjeep Posted April 18, 2016 Baller Share Posted April 18, 2016 Shouldn't a 2012 with the 4.8 have a 6 speed? They list the 4.3l with a 4 speed. Link to comment Share on other sites More sharing options...
Baller Hallpass Posted April 18, 2016 Baller Share Posted April 18, 2016 Been about 12 years, but I rode along with a buddy when he towed a 220 Nautique V Drive from the Bay Area to Lake Tahoe, and back - same truck - no problem. Link to comment Share on other sites More sharing options...
mach1 Posted April 19, 2016 Author Share Posted April 19, 2016 @oldjeep I believe the 4.8L came standard with a 4 speed (6 speed optional) and the 5.3 came standard with a 6-speed. I'll have to verify with the seller though. Link to comment Share on other sites More sharing options...
Baller_ MISkier Posted April 19, 2016 Baller_ Share Posted April 19, 2016 @mach1, if you are really concerned about the transmission, just run it in a lower gear. I have the Tow/Haul mode on the Suburban, but there wasn't anything like that on the Tahoe (4 speed trans). I always towed in 3rd gear with the Tahoe. A bit more gas, but it never labored or shifted excessively. It runs just under 3000 RPMs at 75 mph. I have 267,000 miles on that 20 year Tahoe (I bought it new) and haven't had any transmission issues. I still tow with it and pull the boat 100 miles one-way at least once a week through the summer. The worst slalom equipment I own is between my ears. Link to comment Share on other sites More sharing options...
Baller Mastercraft81SnS Posted April 19, 2016 Baller Share Posted April 19, 2016 You can tow it no problem. I have towed my Mastercraft with a 2wd v6 S-10 with no problem. Link to comment Share on other sites More sharing options...
