No matter how attractive the toy hauler is, if the parts you cannot see are not well constructed it may not be good value. As a trailer or fifth wheel that is carrying extra weight in the garage, you would do especially well to look at the chassis of any toy hauler you are thinking of buying.  Taking the vehicle to a competent mechanic should be a part of your purchase agreement.

You may not be able to see the chassis of the toy hauler, but a well-constructed one makes the difference when you are riding down the highway with a full load of toys. The best chassis is one that is custom made to fit your specific motorhome. A semi-custom chassis is an already made chassis modified to make it stronger. Both are a good choice.

The frame is another important component that you cannot see. The best ones are constructed with steel beams, and have support from cross beams. With your toy hauler, you need strong frames due to the weight you will be pulling. When you look at the walls, search for either wood or aluminum, both hold up well unless they are spoiled by moisture, or in the case of wood, bugs. Find out how the inner walls are constructed.

Check this out yourself. Talk to some RV manufacturers to find out how they build their motorhomes, and shop around. You may be able to buy a great used RV for sale by owner, or find a dealer who sells used toy haulers. It’s worth your time to investigate.
