I am tried of traveling without my car. We are always renting a car whenever we end up where ever. Which is okay, but, there are times when I would like to park the MH and drive back into some unknown area while driving down the highway. Dollies are cheaper then buying a tow bar, Remco pump and a braking system but then you have three things to worry about at the camp ground and another license tab. Question: Can you back-up with a dolly. I know you can't with a tow bar. Tow bars, pump and aux.brake seem to be the way to go, but which ones. Seems that they all have their advantages. However, I do like the SMI Air Force One braking system. I can have that installed with labor and tax for under $1300.00. I am stuck with the Remco Pump because of the front wheel drive. Tow bars range from $200 to $1100.00 but which one. Any advice would be welcome.
