older n you obviously lol but to be honest, I saw those tv converters on happy days, NOT in real life lol....
Sorry CG: but there IS such a thing as dignity and like I said, would you put streamers on the handbars on your bike? No? well, I wouldn't be caught DEAD with one of those cargo extenders on my "truck". Though it might work for you since, ahem, you know where I'm going lol.......
I mean, if you want cheap you could simply get some styrofoam blocks and carve them to the shape of your roof and the kayak then strap the thing on. Least it wouldn't look like you driving around with a kayak up your ass lol.....
Things like those bed extenders remind me of the nobs who drive around with a mattress duct taped to the roof of their car and it's flapping in the breeze.
But hey, it's your...ahem....truck, wtf do I care? lol.....but I tell ya, if I see ya? I'll be looking, pointing and laughing my ass off. But please, DON'T put streamers on your handlebars or a white plastic flower basket. That'd be too much for me, I'd probably bust a gut lol....
