On my last trip I had a blow out and luckily I was still in cell reception for AAA. Didn't think much if it, but I realized I don't have a jack. There is one dinky one in my 250, but I was looking for something semi light and or portable that I can keep for those scenarios where I don't have reception. Also, anyone know if u can put tpms on your trailer? If so, can anyone suggest a brand or type. After my blow out I was a nervous wreck every time I heard something. Luckily the tire damaged the fender skirt around the double axle, bent the metal support and broke off where the support mounts to the skirt...figured blow outs will happen, not sure if I want to spend the money fixing it the new way, I may just bend the support and maybe drill through the skirt and into the support?
