Do I need use one or two X-chocks? I have always used plastic wheel chocks to keep TT from moving when camped but like the between dual wheel X chocks.
Throw the cheep plastic chocks in the nearest garbage can, get 4 of the hard rubber chocks from harbor freight. Set the chocks properly,I set the rear chocks and slightly back into them then I set the front chocks put the truck into neutral and let it set into the front chocks the put the x chock in.
