Cargo Box to put on roof rack of vehicle, originally purchased from Canadian Tyre. 18 cu. ft. capactiy Dimensions: 54" L x 39" W x 19.5" H (139.7 x 104.1 x 35.6 cm) Designed to hold up to 150 lbs (68 kg) Original cost approx $340 including installation kit which had to be purchased separately. Unit is still available from Can Tyre. Purchaser will need to collect the item from Lantzville, payment on collection. Unit is in good condition, purchased for Alaska trip to provide extra baggage room, used maybe 3 times since. All U-bolts and keys are present and correct. Instruction manual is VERY tatty as I accidentally left it in rain, but installation is very simple. Would prefer phone call to email, but both will work.
