I was contacted the other day about an interesting sale here in Northern California that you might be interested in. Jennifer Coleman says her brother is offering mobile school rooms, axle sets, tongues, wheels and tires, as well as trailer beds for sale. They are located in Rohnert Park, California and available for purchase. These have the potential to be the base of a small or tiny house. Worth a look in my humble opinion.
The prices are as follows: $150 for four tires; $400 for two axles with a frame ;$250 for each tongue ; Modular school houses $20 per square foot.
