We would like to buy a reasonably priced portable satellite Internet system and install it ourselves.  We would use it at our house for 6 months and then take it on the road in our 5th wheel for 6 months in the south.  However after searching the Internet for such a system, we only found one dealer... Maxwell Satellite.   
Questions:  Is anyone familiar with Maxwell?  Are there any other dealers that allow you to install a portable system yourself?  We are both computer literate and electronically inclined.    Any help or suggestions would be appreciated.  Thanks!
