Bying a used Rv
I have been full timing in an RV for the last year and I can tell you that there are so many things to look for in a used RV. The first thing I would suggest you do is to check the year in which the tires on the RV you are looking at were manufactured. They may look new but that may be because of l0w mileage or tire dressing that was applied to the tires to make them look new. RV tires tend to fail do to age more often then they do to use.
Be careful of RV's with low mileage. It could mean that the RV has not moved or been used in quite a long time. The problem with a lack of use is that things tend to freeze in place when not used. Valves stick, bearings will develop flat spots due to sitting in one place , other items will rust. Make sure everything on this RV works before you buy it. Many dealers will tell you not to worry about these things, just buy an extended warranty. The problem with this is that if there is a problem do you want to spend time getting your RV repaird or spend your time using it.
Something else to look for are after market items added to the RV. For example, there are systems you can have installed on the engine to supposedly help with performance. Who installed these items? Some amateur that didn't have a clue as to what he was doing. The last thing you want is a major engine problem. Watch for plumbing changes. I have seen rigs with water pumps installed that produced to much pressure for the system. This leads to water leaks and other major water problems you don't want.
Make sure you check the roof. Is it a rubber roof are fibreglass roof? If it is a rubber roof, how old is the rig and will the roof need replacing soon. If it is a fibreglass roof, look for cracks or repairs that have already been made. The roof is one of the most important items to you RV. If the roof leaks it can ruin your furniture, clothing, food, and don't forget about the electronics. Today's RV's are heavily equiped with electronic gadgets besides the TV"s.
Make sure you take the RV for a ride if it is a motor coach and see if the dealer will let you try and tow it if it is a fifth wheel or camper. If it is a coach you are looking at make sure there is not to much "slop" in the steering wheel. If the steering wheel feels loose it could mean that there are suspension parts that need to be replaced. Does it pull excessively to one side. Most motor coaches will tend to pull slightly because of the shape of the road you are on. If you are pulling a fifth wheel or camper make sure that it is tracking properly behing you. If it is tracking "dog legged" it may be due to the axle or axles being out of align with the fifth wheel or camper.
One last thing I will mention, to some this may sound a bit silly but, sit down on the toilet and make sure you knees don't hit the door!This is true whether you are buying a used or new RV. It really is improtant!
