Review on Trailer Valet RVR 9 000Lb by Kazuki Vong

Looks sturdy rather heavy. I have no doubt that this unit can tow a very heavy trailer. However, this only works on smooth surfaces such as concrete or asphalt. A solid surface is absolutely necessary to get the required resistance to movement. It's simple engineering and I'm an engineer and contractor. The gravitational drag under the machine is insufficient when operating on grassy mud or gravel. It seemed to work great on concrete, but all my followers are on gravel, so it's completely useless unless I want a $4500 Sherman tank to dig a nice big hole. I would not recommend this device unless the site description states that it only works on asphalt and concrete. otherwise it's just a toy that digs holes
