I will be genuinely surprised if oil isn't back up to $125-$150 a barrel by Memorial Day, and gas prices are back in the post-2008 oil range of $3-$4 per gallon. People are not that stupid that they will trade their car in for a SUV, like what happened in the 1980s and 1990s during the oil glut. The economy was far better back then as well.
Don't forget the EPA, which tends to be heavy-handed, and tends to severely over-regulate (as they did with diesels, which have made all recently made diesels notoriously unreliable until the car companies can get the technology to handle the Draconian emissions standards.) Same exact stuff happened with gassers in 1973, and it took until the 1990s before most cars actually had horsepower again.
As for my RV predictions, which sort of echo previous posters:
1: European RV appliance makers like Truma are starting to get into the US market. One appliance now can do water heating, and furnace duty, running on both propane and electric. This changes a lot because there is now more space available in a RV, just because one appliance does the work of two. Over time, this will get even better. We may see hydronic systems that use propylene glycol and have that run via pipes around plumbing, tanks, and even have radiators for outside storage compartments to keep those above freezing.
2: As per #1, when Truma starts shipping their VeGA propane fuel cell in the US, the absorption fridge is done for, period. With the propane fuel cell providing wattage to the batteries, a compressor fridge will easily work, and work just as long as an absorption fridge, but without the self-destructing attributes, and able to run 30 degrees from level, not three.
3: We will see the RV industry a move to Euro style RVs, except with slide-outs. The Winnebago Trend is the first shot across the bow in this department, with more to come. This will happen, especially once Ford gets heavier duty Transit chassis models out, likely with a turbo diesel V-8 as one option, and an EcoBoost V-8 as another. Fiat's expertise are transmissions, so I wouldn't be surprised to see a ProMaster chassis with a nine speed automated manual transmission. The Sprinter will most likely wind up remaining as the flagship chassis just because of the name and engine advances, especially if they offer factory 4WD on cutaways and stripped chassis models.
4: We will see ever fancier setups for batteries and power management. I wouldn't be surprised to see lithium battery banks, many thousand watts of solar, awnings on both sides that come out that have flexible panels on them, solar window tint, and larger inverters.
5: More entertainment stuff. I can see some larger rigs actually having a computer with a file server for streaming movies if an Internet connection can't take it, more televisions (so far, the fifth wheel with six TVs was the most I've seen, but I am sure that will get beaten.)
6: For most rigs, same old junk-tastic rubber roofs that rely on gobs of Dicor to keep the rain out at the seams. Since some RV makers are not using Azdel and are back to luan for their fiberglass sides, delamination will be constant boogeyman unless one ponies up for the higher end stuff.
7: At the minimum, beefier batteries to support the ability to charge laptops, cellphones, tablets, and other electronic items while on the go.
8: Special nightstands for the iWatch. When that Apple item comes out, virtually everyone and his/her brother will want one, so having a special place, explicitly for that gizmo, will be expected, just like 12 volt and USB charging ports are now.
9: More innovations for maximizing room inside, be it drop-down beds or other means. Since the more fuel efficient rigs have a weight limit, a drop-down loft bed is a lot less weight than a bed slide.
10: All these predictions depend on the economy. If another 2008 happens, all the above is out the window.
