Now would be a good time to double check your trailer frame and tongue for little dings and nicks. Sand off any surface rust and hit with a shiny black spray paint
... in hard to reach spots, I use a little artist's paintbrush.
My 17 foot rig had a fold-down step ... the front of the metal step housing takes a real beating ... so make sure, if it applies, you check that.
No sense letting little rust spots fester all winter long ...
An ounce (gram) of prevention is worth a pound (kilogram) of cure.
Besides, it will give you something to do this weekend if you aren't going camping.
And if you are going camping this weekend ... more power to you.
When I run down the road, I carry a can of spray paint
with me so I can touch up the frame when I notice a rust spot or two.
