I would not strip a trailer because when you want to sell it buyers will want it equipped. Also hot water and good food and drinks are awfully nice to have.
Well re-sale is one thing, but to me the key is that one's vehicle is rated to tow a certain amount, generally for a reason, and so unless you want to get a different vehicle, you are limited to that amount, plain and simple.
So one might have to either go without certain luxuries, or get a different tow vehicle.
It all comes down to the weight
vs. the rating.
So in trying to lighten the load, a person is usually trying to get into a trailer that is close to the rating, but yet not go over, which is a valid enterprise, I think.
Anecdotally towing an unsafe load with no problems: It's a good thing that there were no problems, but that doesn't mean it is categorically safe, in my opinion.
