Just for fun - RV's in 30 years...
So, DW and I are about 25-30 years from buying our 'retirement rig.' Last night, that got me thinking. When I think of what our TT has that was not part of trailers 30 years ago (multiple televisi...

Sorry but hybrids will do next to nothing for RV's. For short trips like busses and garbage trucks they will work great. Rv's just won't cut it. There is a reason a Prius gets good mileage in start and stop traffic but on the open road not so good.
LI batteries have reached their limit. This means they can't get anymore power out of them or they can't hold anymore power size for size because of physics. Batteries are at their limit. This article takes about how batteries are at their limit and their is no getting better.
Much the same way with ICE's. All the big gains are gone. We went from carbs to TB to bank to bank injection to sequential injection to DI. There is nothing beyond DI and we are now burning 99.?%+ of the fuel that goes into a cylinder. I smogged my Beamer the other day and it has 0 emissions coming out pipe at idle. 0! :E We have used all the energy that is in a gallon of gas. There is no more.
This link will show you how companies like Tesla; aaaaaaaaaa, how do I put this; fudge the truth about electric vehicles.
The bottom line is, it takes a LOT of energy to move a big box down the road. Whether that energy is in batteries or gasoline or diesel or propane or whatever fuel you choose; you will need lots of it. Most of it does not have to do much with weight. Most of the poor mileage Rv's see is because of aerodynamics, so maybe what is old will become new again? Maybe the Hi-Lo will make a big comeback?
I have to disagree. IMO a 250hp diesel + 200hp electric should easily be more fuel efficient than a 500hp diesel. And try to imagine pulling in or out of a campground on silent electric instead of hearing all the complaints of idling diesels and the fumes.
Energy density of batteries might be at the limit but cost of production still has room to decrease to allow better cost effective storage.
And BTW Broder is an idiot. He NEVER fully charged the Tesla. He was even charging when the car said he could NOT make the distance. What does Broder do? He disconnects and drives on. The Tesla goes further than the estimate but still not far enough to avoid the tow. Do you put 10 gallons of fuel in when you know you need 20 gallons? Broder is an idiot. And I don't think Broder ever talks much about the electric vehicle is so low cost to drive Tesla provides FREE long distance fuel with purchase :E Can you imagine any gas burning manufacturer doing that?
