Warwick to Casino

i recently towed my old caravan (13ft Millard poptop from the early 70's) from Brisbane through Beaudesert, out to Rathdowney, then onto Woodenbong Urbenville, Bonalbo and down to the Bruxner Hwy before turning right and heading to Rover Park just before Tenterfield.
the stretch of road between Rathdowney and Woodenbong is good but windey, some of it closer to woodenbong has recently been resealed. i think the stretch between Woodenbong and Urbenville was also not to bad from memory, but the run from Urbenville to Bonalbo is quite bumpy and potholed. in hindsight i was probably driving it abit to quickly (actually i was driving it way to quickly), and paid the price with loosing a cupboard door off of our pantry and spilling some stuff over the floor, luckily it was just sugar which cleaned up easily enough.
the road straight through to Kyogle will definately be more caravan friendly, but if you take your time then the road through to Bonalbo will be alot more scenic, i really did enjoy the veiws along that stretch, even with a few minor disasters. i'm not sure what the road is like heading east along the Bruxner, heading west towards Tenterfield it gets quite windey and hilly.
