I have gone through 2 chevy express vans and am on my third in the last 30 years of modeling. They have worked just fine with nothing but tires, batteries and mufflers until they died of old age. They are really handy. The wife and I use them for travel as well as local model hauling. When you go on vacation you just keep throwing stuff in until most of your household is there and go. No need to plan what you want to take, just take it all
