Fantastic engine. I towed with a 454 for years, thought there was no substitute for cubic inches, not so anymore. 454 couldn't match the 6.0 (366 cu)
Had an '05 Roadtrek based on Chevy Express van w/6.0, 3.42 gears. Roadtrek weighed 8,000 lbs. No problem, even got 17mph. Then started towing a 5500 lbs Rainer travel trailer, no problem still, got 11 mpg and go as fast as I wanted. Ran in cruise all the time except the steeper passes. Oh yeah, always ran in tow/haul mode when towing. Also towed my Chevy car on a U-Haul car hauler trailer, so that was probably even heavier than the TT. I was absolutely amazed at how much power that 366 had.
As you can see you is not alone. I'm 70 and still doing that kind of stuff, seems like I should have figured it out by now.
My dumb move: Bought a new TT in Las Vegas, towed to a paved casino campground to try it out on a nice clear, calm sunny day. Put the awning out (kind of a necessity in Las Vegas to reduce sun stroke), couldn't stake it down on the asphalt, but was no wind so didn't worry. Headed into the casino for dinner (we don't gamble). Came out and awning was on top of trailer. A rogue wind had come along and flipped it up and over. Didn't damage much and was able to fix it myself. DW wasn't pleased. Then there was the time in Las Vegas where we stored the trailer for a month and forgot to unload the fridge.
First, it's an Atwood so not working right is normal. (Their furnaces sound like an F-18 taking off from an aircraft carrier). This from 27 years of TT experience.
The last trailer I had had a replacement Atwood HWT that kept going out, turns out that the curved burner tube was too short and didn't go into the unit far enough. Real poor quality product. Replace with a Suburban.
Been towing for years (since 1988) with a '65 Chevy Van and the standard WD hitch has been working well. Recently bought an '04 GMC Envoy to tow 22' Tahoe TT, mainly cause it has A/C and the van don't.
The old WD hitch doesn't seem to work as well with the new TV-TT combo so thought I'd get another Equal-I-zer (had one once and loved it). While looking around on the internet saw that there is a cheaper Fastway E2 hitch that uses the same anti-sway concept as the EQ. Anybody use these? Are they any good?
Also, anyone else towing with a Trailblazer or Envoy?
Although I've been towing for years, and have always had a transmission cooler on every tow vehicle, I can't remember whether the fluid should come from the trans thru the cooler then to the rad and out back to the transmission, or vice versa?
In other words before or after the the radiator?
Recently purchased an '04 GMC Envoy to tow our 4000 TT, has tow package but no cooler. On the Trailvoy forum, there didn't seem to be a consensus as to which way it should be. Since those using their Trailblazer or Envoy for towing was a minority, I'm thinking us RV'ers here would know best.
The climate you live in seems to be the reason for placing the cooler before or after?
Thanks much all. As usual the response is mixed, and that's what I hoped for to hear the good and bad. rjstractor hit it right on, the 292 is full of torque but light on HP. It's a remanufactured long block I installed in 1988 with a purpose built TH350 tranny. It does slow down on long hills, but just keeps pulling with no pinging all the way down to 40mph. The only time I have to shift into second is the 6% part of mountain passes. We've as far east as South Dakota and to Disneyland a couple of times. Never has broke down.
The wheel base is only 90 inches but with special anti-sway WD bars I invented there is no sway whatsoever (eliminated the chains). It is a lot of work towing with it, brakes aren't real good even though they have been rebuilt, gotta pay close attention front and back and start stopping early. We usually take the blue highways and go 55 mph. That was the speed limit when I built it.
But I love towing with it, we get lots of thumbs up and we are the center of attention at campgrounds.
For a while had a 454 '88 Suburban we towed 30' TT's with and an '05 Roadtrek with 6.0 engine we towed with also. I actually prefer towing with the van.
Sooo, almost anything will be easier to tow with. Don't mind slowing a bit on hills. Sounds to me like the Trailblazer will do us just fine cause I don't expect blazing speed and my antisway bars will keep it straight and level. Since some of you have been successful towing with it, that's good enough for me. Being a pretty good mechanic and maintenance freak, I should be able to keep it on the road for a while. I guess the one thing I worry about is will the engine and trans with over 100,000 miles typically be too worn out to tow well? (I know it depends a lot on maintenance). Is the 4.2 I6 considered a truck engine?
Anybody tow with a 6 cyl. Chevy Trailblazer? (could get by with a V-8 if necessary, love 6's)
We've got a 2004 22' Tahoe Lite we are currently towing with our 1965 Chevy Van w/292 inline 6. Been towing with it since 1988 all over western USA with no A/C. 25 years ago we could handle 100 degree temps. I still can but DW needs air.
So, since the '65 is my daily driver and will never get rid of it (DW says she is going to bury me in it), we've thought of selling her car, an '08 HHR and buying a medium size SUV that could tow the 4,000 lb Tahoe and also be her daily driver. That's why I'm considering an early 2000's Trailblazer.
If I can tear myself away from Chevys, maybe a Durango? (No fords or foreign cars).
