I am handicapped in that I have back problems, some days beter than other, I used to operate a catering cart and take them to (Push) my clients and it wore me out, lifting and removing from my truck. Now I’m on my last few thousand and I want to turn it around and possibly buy a hot dog cart on a trailer, this way there is no pushing or pulling. All is hauled on my truck via the tow hitch. Is this extremely physical???
