We are looking at toy haulers. The truck handles the Jeep fine on a trailer, but I am a bit concerned about preformance with the addition of the toy hauler.

I am mostly concerned about overloading it or having a catastrophic failure 1000 miles from home.

The only troubles I have had with it are transmission related or a bit of black smoke at wide open throtel..

It all boils down to how fast you want to drive. The 6.2 has good bottom end torque, but runs out of steam on the hp curve. When towing heavy loads, the 6.2 usaully has a sweet spot(mine was usually around 62 mph) trying to go faster will usually just result in wasted fuel. Lower gears help some, but for heavy loads and speed, a turbo is the only way to fly.:eek:

I just don't want run over on the freeway. The hauler weiths in at 6500lbs and the Jeep would add another 2500 with gear... So 9000lbs loaded.

Seems like alot of weight for the way my truck pulls, course the only real problem is slow!!

For that kind of weight, you need a turbo!
Are you sure your jeep only weighs 2500 lbs? Both of my jeeps have weighed over 4000 lbs.:confused:

No I am not sure,, better check that out closer...

Dang,,, I thought I had a truck that could pull what I wanted....

Rio,
How about updating your signature so I can see exactly what you have and then I can make a more educated recomendation.:rolleyes:

I have an 86 Surburban, 1/2 ton with helper springs. I pulled a VERY HEAVY loaded 31' Airstream from North Washington State down the West Coast, across the mountains in NM, Ariz, Texas and down to Florida. It is a "stock" 6.2 - very old, tired, been froze-up once - and I am on my third set of heads (this time I got re-builts, not old ones from junk yard. And, I'm not going to use a thermostat - it's that sudden jolt of cold water in zero weather (I'm now in Ohio) that cracks # 1 and #8)

Back to the towing - There is the fast car lane up the mountains, the slow truck lanes up the mountain - and the side of the road for going up the mountains. The slo' lane trucks passed me like I was standing still. And, I blew out a clutch fan - a new one helped cool the engine - otherwise it was near 220 - 240 at the top of the mountain. Ouch! You are right!

When I got to Ocala Florida the differential went "cccrrruuunnnccchhh!" and fell to pieces (the carrier bearing was oblong, not round as supposed to be. But what can you expect from a vehicle that may have 1/2 - 1 million miles???)

Then I pulled that same rig - loaded to the gills - to Ohio hills through the Smokies, etc. When I got here the motor spun, so did the tranny - needed re-building - and injectors and glow plugs and injector pump and a starter each year for five years and new radiator. But, I love this vehicle!!!! I have about $15,000 in it - and it's worth about $2500. I've got to talk to my insurance man tomorrow about increasing it's replacement value (no kidding, I am!!) Why buy someone else's junk when I have my own junk - but know what it is!!!

Now, another set of heads - what can i expect from such abuse? But, it got me there/here and there and here, etc. Keep it cool, keep it lubricated (I swear by that slippery stuff in oil - Dura something or another - is it Duralube? About $15 a quart each oil change)

Pull that load - what can you lose? By the way, coming DOWN the mountain was pure excitement!!! I pump those trailer brakes to keep them and the Surburban from the "fade" they get from overuse down a long run.

Well I can't say I like mine as much as you do Dennis, but it is paid for.

Signature Updated!! Thanks again

Still don't see your sig, if you plan on going anywhere where a mountain or altitude is involved, your N/A diesel will really start to upset you.

6.2s will barely pull their own weight with altitude, much less a trailer.

I had one of these 6.2's back in '81. Pulled a small travel trailer one time to western okla. This motor wouldn't pull a peter out of a lard bucket! No power.

Well, I've got my new heads, putting in new exhaust system. The muffler guy told me that the 2 1/2" exhaust back to muffler is reduced to 2" from there back - not good! Too much restriction - could it cause the #1 and #8 cylinders to not scavenge (sp?) the heat out fast enough - thus cracking more easily?

My 6.2 lost its power when I had the injector pump re-built. I suspect it's the timing. Any suggestions for how and which way to move the arrow?

I was hoping for comments re: the running without a thermostat in winter to reduce the cold shock of water going into hot #1 and #8.

PS - what does "no signature" mean? I'd be glad to comply if I knew.

Thanks,

Dennis

My Airstream (31') is about 7000 pounds and I had at least that in musical instruments, books, computers, tools, boat parts - so I'd guess I was pulling 12 - 14 thousand pounds (really!) On the flat desert I could drop it in overdrive - and get that 62 miles an hour - the "sweet spot" mentioned. I really can't complain about that so much as the problem with heads and starters - and now a new radiator. The one I had in the mountains was only 50% efficient and fan clutch slipped 'til I discovered that, then it cooled good.

The insurance man said he could only allow $2000 on this car I have almost $15,000 in now - unless I produced all the reciepts for new almost everything (and now complete exhaust system) But, it's paid for!!!!

Dennis go to welcome note stickys, locked at top of the forum threads full instruction why to do it & how are there

Sounds too heavy for a NA. Won't last too long under those conditions. You will over heat on long pulls and be going 10 MPH. You need a turbo 6.5 or a cummins. I love the 6.2, but not for what you want to pull

I apologize - I just found your response to my note - I can't find the "stickys" you referred to.

I'm having trouble navigating this site - I need to learn it better. Is there someplace to check to have these notifications sent to my home e-mail so I don't miss anything?
