You can drive the unit as fast as it will go.
All you have to remember is!
The higher the speed the longer the stopping distance.
Your reaction time 2 to 3 seconds will be OK provided you are paying attention to what is happening up ahead, if you need to take evasive action or slow down the distance between you reacting and the problem is a lot shorter.
RV's tend to be top heavy, with all the junk that is packed on the upper cabinets they are not the most stable, high speed and some good gusts of wind your ability to keep control will be challenged.
Just remember speed kills, if you have a family, I do not mind if you kill them, they are after all your family, it is all the other innocent persons that are important.
When EMT's and Fire-Rescue roll to a freeway accident they always hope that there
are no small children involved, it is the most heart braking site to see a child that is injured or worst DOA.
