The roof mounts work good as long is there is no trees or other obstructions very rare when camping, a tripod system can be installed in minutes with a little practice use a compass to find an open spot facing South and Bob;s your uncle.
A good tripod makes things a lot easier the $75 tripod is hard to adjust, the key is level the dish and turn to the satellite. I have a TRV tripod I ordered from the US makes life much easier.
