I wish I would have asked more questions before I bought my first (only to date) RV. I wanted a separate RV, not a trailer, not a 5th wheel at the time. I thought I might pull my boat out and go camping, fishing, skiing - never did.
I bought a Class C RV before I knew anything about RVs. I did get a good deal on it as a used RV (for a reason). I discovered the secret issue no one talks about in the RV industry - Dry Rot and Water Damage. I found it by ignoring my senses because I thought I was getting a good deal. The RV smelled musty when I bought it but I assumed that was due to it sitting for an extended amount of time - nope. After a rainstorm I discovered the entire front overhead cab area had been leaking at the overhead window and had rotted the entire bunk and front wood.
As the RV ran great I decided to rebuild the front overhead bunk - and do it the right way! I found that the manufacturer had only used pine framing (with very little metal supporting structure underneath) that was stapled together at the joints. The whole front overcab was ready to fall at any time.
I then set out to rebuild it...
And here is how it looks today...
Now sorry if this lengthy response appears to hijack your thread, not my intent. I am really just suggesting that if you are thinking about an RV you check it VERY CAREFULLY for signs of dry rot and WATER DAMAGE. These things are not maintenance-free like your home roof. They are basically rolling earthquakes that open up and trap water. Granted, my RV is an 89 and things have changed with advent of rubber roofs and the like - but they all need periodic re-sealing and sometimes pressure-testing to maintain their warranties.
Would I do it again? - you bet. I love my RV and will likely not go back to tent camping. What I would differently would be to get a travel trailer. What I find is once I set-up the rig at our camping spot and if I do not have a tow vehicle, if we want to go out and take a drive to explore the area I have to pull up stakes - for that reason my next RV will be a trailer to a 5th wheel. That way I can drop the trailer and use the tow rig as a way to go out to the store, gather wood, or explore.
Good luck on whatever you choose to do.
