- colliehaulerExplorer IIIShape of trailer makes a big difference as well. A Airstream is a lot more aerodynamic then a box trailer and will pull easier at highway speeds and will burn less fuel to do so. The back of the trailer is as important as the frontal area for wind resistance.
- wnjjExplorer IIKeep in mind a boat will tow far easier than a camp trailer of similar weights. The wind resistance is a huge component of towing.
One of the worst loads I’d pulled with my V8 Dakota was a ~2000 lb flatbed snowmobile trailer with 2 sleds on it. The combination of the front shields, a long trailer tongue and stiff winds had the pedal to the mat to barely maintain 55-60 on flat ground at times on one trip.
The same truck pulled a 21’ trailer without much drama, - SoundGuyExplorer

Based on an earlier suggestion I hooked up to my boat and pulled it from Greenville to Ashville. 6% grade over 5 miles. I used trailer tow button.
Towing a full height travel trailer is an entirely different experience from towing a boat on a trailer. You won't believe the drag due to wind resistance that quadruples as road speed doubles, with weight having little to do with it. - SCSignmanExplorer IISorry I also wanted to add that Tran. reached 208, Engine 210. But that was on a mid 60's day. Summer may be higher?
- SCSignmanExplorer IIAgain I appreciate the feedback. Based on an earlier suggestion I hooked up to my boat and pulled it from Greenville to Ashville. 6% grade over 5 miles. I used trailer tow button. Truck down shifted on climb several gears but did not wind out RPMS above 3000 a few times when passing semis. I would normally take it slower but ran 65 without a problem and passed trucks. Boat is deep V 23ft weight on ID tag is 5280 dry. I towed with gear and full tank of gas. Really need to get on a Truck Scale to confirm. However the newer V6 seems to be making a big block V8 guy pretty surprised...Maybe scales will show weight is lighter. I'll post actual data afterwards.
- ib516Explorer IIIt'll do it, but it'll be slow. In perfect conditions, it'll be ok, but load it up, hit some hills and have a head wind, and you'll not like it so much.
Unloaded vehicle weights (UVW) for RVs is only useful when you're shopping as no one tows an empty RV around. Use the RV's GVWR for a closer estimate to the weight you'll actually be towing. 5200# UVW can quickly become 7000# when loaded for a trip. - colliehaulerExplorer III

My V-10 manual transmission truck runs 3200 RPM at 75 mph where the engine makes the most power. It's a lot harder on a engine to lug it at lower rpm then to let it work when towing. 170k miles on that truck and runs very well.The engine is SAE certified to 285 hp (213 kW) at 5300 rpm and 305 lb?ft (414 N?m) at 3900 rpm on regular unleaded gasoline
Yeah, and who wants to travel long distances with the engine screaming at 3900RPM?
Most people freak out if the engine's turning over 2000.
The torque curve on that V6 is very steep/peaky as I recall, meaning it doesn't make much torque until it gets in the higher RPM ranges. You won't be loping along at 1900RPM on the flat ground. It'll be more like 2800. - mkirschNomad II

This is pulling large grade in NCaroline up the smokies with a 5.3 pulling 5500 lbs trailer fully loaded. I dont floor my truck ever. I let the engine work.
1st gear 30 mph and 3500 rpm.
Infact I take my foot off the gas some to keep at 3500 rpm.. Remember I have 4 speed..
Notice engine temps 230f but trans temps with cooler 175f or so.

And this is 2nd gear trying to pull highway grade. Im trying to not let it go into first gear.
30 mph and 2200rpm. Second gear is a dog if you don't get momentum for the hill. But there is nothing you can do. I couldn't speed up.. I could just maintain..
Imagine if I towed 7500 lbs as Chevy says I can??? LOLOL ha ha ha

Lugging at 3500, you’re leaving a lot of HP behind. Spin that motor up a bit. When they spec the tow rating, Chevy probably assumes you’ll actually let the motor run instead of holding back on the go pedal.
Hardley lugging @ 3500 rpm. Im right in the torque band. Why gas it up and rev to 4000 to go 5 mph faster. If I let it shift to 2nd it will dog and kick back to first anyway..
I wasnt struggling in that first video. I was just letting the engine work, and that was a comfortable RPM and speed for me.
Since the 4l60 trans has such a low 1st gear I can pull any grade with 6000 lbs on the hook. Not fast but it will do it.
But as in the second video I was lugging there a bit. It was an in between 1st and 2nd gear thing... Oh I wish I had a 6 speed, but it is what it is...
But to the OP, you will be fine IMO. - wnjjExplorer II
