I really think that V-8's are pretty much obsolete except for very high performance and race cars.
Cr@p. It's called "reliability". You get more performance, more easily and with less wear and tear, out of a V8; simple as that. When you have to use blowers or turbos to stuff air into an engine, that means extra stresses and, usually, much higher RPM, to make the same numbers. The =main= reason that race engines are only 4 cyl, is to =limit= performance to =limit= speeds. Just like NASCAR uses restrictor plates on the super-speedways. Yes, we =can= get huge numbers from small engines, but I'll put up my 350 hp Genesis Coupe against an older Corvette, with the same output, and that Corvette will simply leave my Genesis in the dust. People forget about torque, which lower-revving V8s have the lock on. Why do you not see pickups with V6s in them to tow anything more than about 8k lbs? Simple, you just need more torque and performance than a V6 can give.

Workers have become lazy and don't care, even the sales staff has become lazy. We just spent three days at the LA RV show looking at new units. Now when I did sales, it was part of my job to me to clean up/fix up everything for sale. So that the customer saw was the best product for sell.
Now you walk into a RV with sawdust in almost every cabinet, loose screws and all the say is "well it has to be cleaned up the workers aren't that good". You want to sell a 50 to 70 thousand dollar unit and you can't even pick up a dust pan. Sure I trust your word and service department.
Explains why we have been looking for the last year for a new RV.

As a bit of a "car guy", I'll firmly dispute your statement that v-8s are obsolete. If they were, don't you think that race cars would all be running 4-cyl engines?
Indy no longer races V-8 engines.
BTW, when the GM vice president of drive train development was discussing a decade previous development of 70 HP/liter engines in the mid-1970s, he was also discussing development of variable valve timing and electrically driven valves (manufactured by Magnavox - yes the TV company). Those technologies were that old and stifled when business school graduates started designing cars in the 1970s.
Nardelli was running Home Depot into the ground. So they paid him $200 million to leave. Nardelli does what business school trained management does - enrich themselves.
Nardelli then ran Chrysler into backruptcy by doing what business school grads do. Nardelli's manaagement company is now running Acme Supermarkets where store close to make spread sheets look more profitable.
Is Nardelli knowledgeable of hardware, autos, and groceries? Of course not. He understand cash flow, cost controls, and other support functions. Therefore innovation was impossible. Costs increased. Innovators were stifled. Management padded their compensation packages. Employees and customers became victims. Nardelli got rich at their expense. He did what is taught in business schools.
Remember Flint's water? All key decision makers were business school graduates. Flint was created by cost controls.
What is the employment experience of each RV manufacturer's top management?

To increase quality, Quality Control (QC) inspectors are eliminated. Those simple concepts are obvious when one comes from where the work gets done.
A business school graduate was taught that a trade-off exists between costs and quality. Increased quality always means decreased costs. Concepts difficult for a finance guy to grasp.
Any car that still has a six or eight cylinder engine is using obsolete technology. Since innovations (demonstrated by GM engineers in the early 1970s) are standard all over the world. But GM still needs large front ends (ie SUV) to house obsolete technology V-8 engines. GMs high costs, blamed on unions, are directly traceable to GMs lower quality. Because a spread sheet says innovation increases costs. Reality says otherwise.
Chevy Volt is the only hybrid where the engine cannot recharge its battery. Done intentionally to decrease costs.
Those concepts apply to all industries.
