Hi my name is Ron & I am new to the forum, but I need help with a question, I bought a Rugged X & every time I tow my caravan on concrete road it’s like driving on a real bad corrugated road, it’s so bad that I can’t even take a drink from my coffee mug, it’s as rough as guts, I have spoken to Toyota but they say it’s the first time they heard of this problem & cant give me a reason, I was thinking of putting ARB suspension but I am a bit reluctant because I don’t know if it will solve the problem, so I would like it if maybe someone has heard of a similar problem that can help cheers Ron
