Since my earlier post , we've had three seasons with the TT. I'll add more tools. I've had to repair the power stabilizers, three times,now.
Ideally, you should never have to use these tools, and if you do, just don't be seen with them, so they don't have to be Snap-on. One of those Craftsmen, Stanley or Canadian Tire 200 piece sets for $79.99. But check them out,150 pieces seem to be screwdriver bits. SAE and metric. I found I needed metric allen heads, I had them. Punch and chisel set, I needed a pin punch, too. Harbour Frieght stuff. Larger sized combination wrenches, those sets stop at 3/4" or maybe 1". Plus screw drivers, pliers, vise-grip,10" or 12" adjustable, wiring kit, voltmeter, and torque wrench. Star lug nut wrench sized for truck and trailer. Our trailer has 3/4" on the axels and 13/16" on the spare. Hydraulic jack and Pad.
Chainsaw, genset for battery charging.
