Ladies and gentleman, I happen to sell equipment for a living so when I read these accusations to never believe a salesman or saleswoman it makes me wonder why a person would say that. It is a consumers responsibility to do some homework before you go shopping because you will become very confused with all of the information being presented if you do not. The equipment I sell is very high dollar and it is my responsibility to never lie to a customer and have some idea of what I am talking about. It is always better to have the option to talk with a manufacturers representative about high dollar purchases especially an RV. These people are trained on that product and not additional other brands of equipment. They typically can answer more complex questions than the average sales person. I welcome the opportunities to travel and work with any of my manufacturers reps since I have about 20 manufacturers to represent, as with most RV sales people. There are too many complex systems built into your motorized home on wheels for the average consumer to have a complete understanding. You have the chassis with all of the wiring and electrical systems then the drive train, the the 120 volt house electrical system, the water heater, the refrigerator, lighting, leveling systems, TV's, stereos, the furnace, air conditioner, the sanitary systems, then there is the construction of the living quarters and on and on.
Ask yourself before you start shopping, how skilled are you at understanding, diagnosing, and/or repairing any of those systems on you permanent residence, then give less of an assumption about your skills when it comes to ownership of a house that you will actually be driving down the road and possibly running into someone else.
Sorry for the hijack but when I read comments about NEVER trusting a sales person it takes me to the uninformed consumer mentality. If you encounter a sales person you feel is uneducated or less than trust worthy move on and find one you feel comfortable working with and stop blaming other people for your misfortunes.
