I received this question the other day and I thought it might be helpful to anyone else that may also be looking to tow a vintage trailer with a 4 cylinder car.
Question: “I’ve been seeking a vintage trailer (10-14 ft) that I can pull w/my 4 cylinder car. There must be a bathroom.”
Answer: “A vintage trailer of the size you are looking for that has a bathroom may be pretty hard to find unfortunately. I’m not familiar with any that small that have bathrooms as back in the day they just didn’t make the small ones with bathrooms. It’s much more common to see bathrooms in larger models such as 16ft and above. Although in a small trailer, if it has a closet you could use a porta-potty. I have also seen where people have modified the closet area and installed a plumbed bathroom. So that may be an option if you are willing to put in the effort and cost.
As far as towing with a 4 cylinder you’ll want to check the tow capacity for your car and see what it’s rated at and also see how much tongue weight it can handle. I don’t want to sound like I’m raining on your parade but towing with a 4 cylinder will really limit what you can tow. To give you an example, our Shasta Compact is 10 ft (13 including the tongue) and it weighs 1160 lbs. This is the dry weight. If you pack “stuff” in the trailer and in your vehicle that overall weight is greatly increased. I know you could tow a tear drop but those are really tiny and it doesn’t sound like that is the type of trailer you are looking for.
The major problem with towing with a under powered vehicle is not so much that you can’t go down the road and pull the trailer, as on flat surfaces you likely could, but it’s the long term wear it will have on the cooling system, transmission, brakes, etc., that you have to be concerned with. Plus it’s probably just not real safe. It’s just really hard on a car to tow something over the rating capacity. I’d recommend you look up on Google the tow rating for your particular car as maybe you can find some info. Or you could talk to a dealership as they may have some info. I think if you could upgrade to a larger tow vehicle you would have many more options for what you could tow.
I hope some of that is helpful.”
