I have owned a Class A, 5th wheel and my current trailer. Never really had much problem with them. Fixed few leaks here and there, one circuit board on the fridge, one slide out on the current trailer and one failed wheel bearing on the current trailer. We camp about 10 to 15 times in the summer and sporadically through the winter months here.
It is up to you, but I couldn't imagine not having one. We unplug and do things together as a family. That is priceless.
Lots of people who don't own them like to chime in and that is fine everyone is entitled to there opinion. Like anything they have to be maintained.
Old Harvey the RV Modified 454 air ride, super blue suspension.(1988 24 foot Fleetwood Southwind Chevy P30 chassis) It was a hotrod for an RV. I owned him 5 years.
The old 5th wheel (1995 25 foot Fleetwood Prowler )with Big poo(89 GMC 1 ton). Was a great little bunkhouse. I bought it for 3500 bucks. No issues. Had it for 5 years. Yellowstone, Yosemite, and all over Wa and California. This was in St. Regis Montana in 2010.
And my current 2012 Keystone Passport 32 foot 7800lbs loaded Bunkhouse. With the old truck. Lots of good memories with this one.
I have towed this trailer close to 28,000 miles.
My kids absolutely love it, to be honest so do the wife and I. Being on the road for 6 months out of the year is how we see our retirement.
