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.
My BAL adjustable chocks (2) locks all four tires. Dropped the Cummins/NV5600 tranny in 1st gear and slide all four trailer tires....on a tug test bet. I've seen others forget a plastic/wood chock usually on the passenger side of vehicle (MH...TT...truck...trailer). You can hear the engine spool up more than normal then watch the vehicles tires roll up and over the blocks.
