I have wanted a 5er for a few years. I just love the room, would be especially nice on rainy and colder off-season days (we camp in Maryland from March to late Nov.). With the right 5er I could camp comfortably year-round in the mid-Atlantic. BIG tanks, again great for boondocking (maybe I could get rid of my blue tote tank!). I am a gear head and like all of the storage too. Many are prepped for generators, that would be a plus as we "boondock" 90% of the time. All in all, I think they offer pretty good bang for the buck.
However, they are so darn big and can limited the campsites you get into (we camp in mostly state parks). To me they look stupid and ungainly coming down the road. They shoot your already bad mileage too Heck. Furthermore, we carry bikes, kayaks and a canoe at times. 5ers make that difficult. Also I like having a cap/topper on my truck, we use that feature a lot, plus I had A.R.E. mount rails on the top of it at the facotry for my Thule bars. A good hitch for my shortbed, like the Superglide is expensive. They are SOB's and will start to look like crap in a few years and start to show wear pretty quickly unless you purchase an expensive deluxe model. I think that is part of the price you pay for the "bang for the buck".
We were looking at 5ers this past weekend. i told my wife that in the past I used to get stoked when I looked at them, but now it's kind of been there, done that with SOBs. I had a mild case of aluminitus a few years ago, but then I purchased my SOB. Which has been a pretty good trailer all in all (but for a roof leak that messed up my back ceiling...darn I need to replace that panel). I think Jayco builds a pretty good trailer for the bucks and they have about the best warranty in the business (I guess they still have the same warranty I had; 2 years bumper to hitch and another year on the structure, about the best in the RV business).
Also with the whole oil deal, I think I would feel better towing something with a lower "profile" with the added benefit of a bit better fuel mileage.
BTW I don't agree with the poster about the interiors. They must not have looked at many SOB's recently. A few years ago the interiors were, as we refer to it, too "country cutsie poo"
, but many of the new interiors have great looking designs with earth tones and are very desirable in that regard. Less etched mirrors more nicely stained wood.
It's funny how the larger the RV, the less people it is really meant to sleep. People say about large RV's / 5ers: Cocktails for 6, Dinner for 4, Sleeps 2.
Anyway, I have aluminitus pretty bad at this point, and while I may still revert back to an SOB, I don't think so. It's an itch that I need to scratch (if the economy ever sorts out)!
