I thought UPS was using hydraulic hybrids, designed to optimize savings during stop & go driving. Looks great for delivery routes but not sure how applicable that technology might be to the world of RV's.

Perhaps we're in for a future of aerodynamically streamlined class C's? I'm thinking we're probably a way off from that.

While I am talking about aerodynamic drag, can anyone here take a guess of how much drag is on a rifle bullet, such as an M-16 round?

It's HUGE! Out of curiosity, I once consulted a ballistic table that showed muzzle velocity of a round, and then its velocity at 1000 ft, 3000 ft, etc... I then assumed that the bullet underwent constant deceleration due to aero drag as it exited the muzzle, and computed that deceleration.

I do not remember the exact number, but it was several G's of deceleration.

And many air-to-air missiles decelerate as fast as that bullet after their propellant burn out.

Cool


I'd just noticed the hybrid drive words on the side, and not looked into it in detail.

Class C RV makers do not even bother to round-off any edges of the MH body, except for premium makers like Chinook and some other brands.

Glenn Morrissette of the "To Simplify" RV blog reported something like 13mpg on his Chinook, while I cannot get more than 9.8mpg on mine. And as you probably know already, he is downsizing to a Vanagon, mainly because of his gas bill.

Yes, it's sad. I usually stop at Costco for gas in my RV trips (to save a few bucks), and while I spent 10 min pumping gas and felt sorry for the motorist waiting behind me, he probably felt sorry for me spending that money. And I have read of an RV'er with a big class A (a converted double-deck bus) holding 300+ gal of diesel.

And he got bored with RV and bought a boat with a fuel capacity of 3300 gal.

The lady who lives out of her Prius had it figured out quite well. I like how she can leave her heater on all night, and the engine only runs very occasionally when needed - plus, when it does so, it is quiet, so won't disturb her.

It was that fact, plus the fuel economy, that got me to wondering about the application of hybrid technology to RV's.

Once the same chassis' that are now used for class B's and class C's become hybrid, we might see some of the custom manufacturers such as Chinook, Roadtrek, LazyDaze etc develop new streamlined body designs. I look forward to that day. Actually, on my budget, I look forward to that day + 10 years, so I can afford to buy a nice used one, by which time my RV days will be behind me

But for a single person, you can get a used Sprinter-based class B diesel with decent MPG right now.

Or you can spend the time to build your own travel trailer like this guy who puts enough solar cells on top, such that he could run a small A/C from the solar panels! Yes, that is the first! It requires much better insulation than is in factory trailers.

It worked, but he is ripping the walls out to put in even more insulation. Said it was OK up to 95F outside temperature, but he wanted better.

If you do not know of this guy, search for "over the top cargo trailer". Really cool!

Chuckanut, I have a Lincoln MKZ hybrid. It's sweet!!! It has more room than the
Prius and consistently gets between 39 and 42 mpg over the two years I've owned it. We drove it from NJ to Cape Cod and back last year and it was a dream.
The 2013 model is improved - supposed to get up to 47 mpg with lithium ion batteries.

Go for it! The Lincoln is the smoothest and most spacious hybrid on the road today - and its 100% American made.

How about repairs and maintenance costs? I figure anybody can do an oil change but what happens if the drive train needs work? Is that something only a Toyota dealer can handle? I have a good independent repair shop near me that I trust.

Yeah, I do admit we have plenty of them around where I live. But they are pretty widespread - I see plenty of armadillos in Georgia, for example.

The leprosy carrier thing has been known for a loooong time. I've never had the urge to pick an armadillo up, although their eyesight is so poor they'll walk right up to you if you don't watch it.

The other day I was amused watching an armadillo - he sure looked like he was carefully sneaking past that border patrol vehicle. But he was headed for Mexico!

One more sidetrack on the Prius, some of the tech and Prius sites talk about using the the Prius as a small whole house backup generator. Probably would not consider it with one under warranty but an older model maybe, first by installing an inverter (a large UPS)in the house then using the Prius to charge the UPS. One link to one of the tech sites:

http://www.wind-sun.com/ForumVB/arch...p/t-12962.html

We have a class A with a diesel generator and a Honda EU2000i for emergency backup but still an interesting concept. You could drive the Prius everyday keeping the gas tank full and have a instantly available backup generator without having to worry about storing gas cans, etc.

I've driven an Escape hybrid for 6 years and the good news is that I've never had an issue with the unique hybrid components (I did have some front suspension / steering work done). The bad news is that there are some failures that only a dealer can fix and not all dealers have a hybrid trained tech on hand. So, conceivably you could have a failure in the middle of nowhere and be hosed.

Prius owners are probably in better shape due to the higher sales volume.

And Ford is phasing out the Escape hybrid, replacing it with the Ecoboost in the 2013 model.

I suspect the Prius will prove to be a surprisingly long-lived car with few mechanical problems due to the mechanically simple and rugged planetary gear drive system and the way the IC engine is coddled relative to a traditional car. But I could be wrong, or perhaps the fears of uber-expensive battery issues could still prove true, or perhaps the electric motors and computers may exhibit wear or degradation I don't anticipate. But it looks like a system built to last a long time with no major repairs.

That said, if it breaks down you can't get a jump start or push start and continue on your way.

Over the last 25 years we have had several Toyotas including Corollas, Camrys and Tundras and never had any major components fail, and the 2 Camrys were aged 9 and 10 years with over 100k miles.

We've had our Prius over 5 years now and it has done ~69k miles with no issues except the 12v battery failing after 2.9 years, and the dealer replaced it at no charge (pun intended).

Sure you can get a jump start provided it is just a dead battery. I've had 2 jump starts, once when the battery failed, and once when we let the car stand for 5 days with the tailgate open (and dome light on).

I have also entertained the idea of getting a used Prius, and playing with it this way. Too bad it cannot be flat-towed to serve both as a toad and a generator for my RV. As a generator, it most likely burns more gas than an Onan genset, but surely is a lot quieter.
