: 6800 mile towing trip (NO OVERHEAT)

If I posted in the wrong section, please move this thread...

Well everyone, 6841 miles in three weeks, this vacation is in my history book. Fuel mileage ranged from 14.6 mpg to 9.4 mpg, hand calculated at every fill up. The low mileage was in 113°F heat with a collapsed “Purolator” air filter. I was towing at around 12k lbs., down from the anticipated 14k lbs. The obvious being the cost of diesel! I paid anywhere from a high of $3.29 to a low of $2.87 a gallon. Speeds ranged from 60 to 85 mph (highway). The 9.4 mpg tankfull was when I was trying to "overheat" my truck, holding the throttle to the floor while climbing a steep grade.

We only had two mishaps on this trip. The first being the Turbo Charger hose blowing off while climbing the continental divide east of Butte, Montana. The wife, flipping out wondering what had just happened, was surprised to see I knew what happened and was able to fix it in a few minutes (thank you Diesel Place for all the interesting reading!). This was short lived… The pipe blew off three more times before pulling into Butte. To correct this (until arriving back home), I ended up taking my Vise Grips and flaring out the end of the aluminum pipe to keep it from slipping out of it’s boot. Why does this kind of thing only happen to me on a Sunday afternoon??? I will be visiting the dealer real soon to have the pipe replaced. The other mishap was not one, but two stones hitting my windshield. On I15 where the highway was “tar and chipped” and all kinds of loose stone was in the non-traveled part of the roadway. Someone decided to change lanes, which peppered the car in front of me and gave my windshield two chips (and a resulting crack).

There are those who say, “all LLYs are overheaters”… I DID NOT overheat! In the 113° heat, all I could muster was 243° engine coolant temperature. The fan came on at about 205° and ran constantly until I slowed down and it could cool to 190°. Again, I was towing about 12k lbs. (no, I don’t have a weight slip, I weighed everything going in the camper as we loaded it and added it to the “dry weight”), and was at about 5000 feet +/- elevation. I would be abusing my truck to push it to the point of overheating, (if I could get to that point). Now to be fair, I must say that I did the “Stack Seal” mod before my trip. I also have some “front porch” screening in front of the stack to keep the bugs out of the radiators.

Our trip included Indianapolis, Indiana, to Minneapolis, Minnesota (Mall of America), to Badlands, Rapid City, Mount Rushmore and Crazy Horse, South Dakota, to Devil's Tower, Wyoming, to Glacier National Park, Montana, to Moab, Utah (Arches and Canyonlands NP.), Then back home via Interstate 70.


Improvements? Yes! I will be adding MORE FUEL CAPACITY for the next trip. What a pain in the Censored to have to stop every few hours to fuel up! The nice part was having the "facilities" with you everywhere we went... A bathroom or snack break was just a safe pullover away. The kids were entertained by the just installed DVD system playing on the headrest displays with video/audio also playing through my navigation/Bose stereo system. The added sub speakers made the movies sound like my home theater. Not once did I hear, "are we there yet", (unbelievable), well, I think I heard a couple "how much further"s.

Sounds like a cool trip, thanks for sharing.

As far as the overheating, it sounds like you were losing the battle until you let off of the throttle. A little more weight, a taller trailer, or a longer hill would have done the trick. Even so, there are definitely some trucks that are worse than others and you seem to be on the better side.

Great trip Dreamin'! Thanks for the feedback on my "Wuss" thread. I want to do a similiar length trip, only with the West coast in mind. I like your 5er; any comments or regrets? I don't really need a larger 5th, it's only me and my wife, but I gotta' keep her comfortable... if you know what I mean! ;) Thanks again and congrats on the trip.

My 5th is 27 feet, (30 feet overall). It is a low end unit (cost), being our first real camper. Alot of the accessories in it are cheesy, but we knew it buying it. I specifically bought this model because of the almost full sized shower. I am 6'1" and a full sized shower is a pet-peave of mine. The wife was kind-of ify at first, so spending $30, $40, or $50K was not an option. Now that the wife and kids have some experience in camping, it will be real easy to trade up! The size was perfect for manueverability and would recommend it for anyone starting out. If I go with a better unit later, I will stay with this length or slightly longer. Like I said earlier, the 26 gallon fuel tank on my truck just plain stinks. The moment everyone else falls asleep, your pulling into a gas station to fill up again.

With just two people (you and your wife), I would go smaller (like 24'), but still go with a 5th, stability and manueverability being the main reasons. Hooking up is alot easier also! It's a one man job... Just look out your back window.

I like Forrest River products, our first 5er was a 30' Wildcat bunk model that went to Colorado 3 times, we had no complaints with it, but the kids grew as kids will and the bunk area got too small and we wanted a bedroom slide because my wife has had 2 knee surgerys and the bed was hard to make.
We traded up to a Cedar Creek Silverback and we all really like the new rig.
I also got tired of having to stop for fuel every 3 hours so I added a 60 gallon fuel tank/toolbox combo. I can leave my home and make it to Durango Colorado without having to stop (but nature makes me).
Here is the web site where I got my tank (http://www.zylstraauto.com/).
It was affordable and I can keep all the tools and junk that used to ride under the back seats in there. Photos in my garage...
Hope this helps.

Thanks again Kampzite... Looks like I'm following your footsteps. We were just looking at the Cedar Creek model(s). Don't know when is the best time to trade up though. Now while it's still new and take a hit, or wait a couple years then trade.

I've found a tractor trailer fuel tank, (round, polished aluminum with a big dent in it). I think I can get the dent out, but it's bigger than I'd like (55 gallon drum size). The price is right though... FREE!
