I had a similar experience with a used trailer I repurchased a few years ago. It needed some work, especially on the decking, but after a weekend fixing it up, it was as good as new.
I learned to regularly check and maintain the trailer's tires and wheel bearings, as they can wear out faster...
Yesterday, I did some weeding and added some fresh compost to my raised beds. Last week, I planted some tomato and cucumber seeds, and they're starting to sprout now. Today, I'm planning to tackle some pruning and maybe plant some herbs.
Romanesco cauliflower can be more drought-tolerant than regular white cauliflower. I've grown it in a semi-arid area, and it did pretty well. Just make sure to give it some extra water during the dry spells, and you should be good to go.
