We now have a little real-world experience towing our 1978 Trillium
4500 with our 2022 Tesla Model Y Long Range. I'm happy to share our experiences, but also look forward to learning from others who tow fiberglass rvs with an electric vehicle.
We successfully completed a five day tour through Northern Indiana and Southeast Michigan yesterday. We camped one night at Potato Creek State Park and three nights at Tri-Ponds Campground near Allegan Michigan. We charged at both sites, utilizing a TT-30 adapter.
Two of the travel days were around 90 miles, which was no sweat with our rig. The last leg home was 150 miles, which I think may be near our limit without stopping to charge. Please understand that this is fairly flat Indiana and Michigan with optimal weather.
We did stop to charge once, but that was only because I had left my wallet at home and decided to make the 180 mile round trip home on morning number two. Another lesson learned.
Without that screw-up, we could have completed the trip (and side-trips) without using a Supercharger. I'm glad we needed the Supercharger stop as this was our first experience, and it was great.
As I said, both sites were 30 amp sites. This was adequate for our needs this time, but I'm going to try for 50 amp campsites when possible.
It was a real surprise how accurate the Tesla navigation predicted the energy required to each destination while towing. The navigation shows what percentage of battery
will be left at the destination, and after towing a few miles, it was accurate to within a few percent. If the prediction is too low, the program adds a stop at a Supercharger along the route.
The only problem we experienced was on the first day the Tesla Charging Connector detected excessive heat at the plug into the TT-30 outlet. It automatically cut the current pull in half (12 amps) and sent a warning to check the connection to my phone. I disconnected, checked for corrosion in the plug, let it cool and reconnected (it resumed 24 amp charging). This recurred a few hours later, so I wonder if putting a little dielectric grease on the plug contacts might have prevented this.
Prior to the Tesla, we have towed with a 2015 Honda Odyssey. Both have a 3500 pound towing capacity, but the Tesla seems more stable and is all-wheel drive.
The Odyssey has the advantage of a large cargo area, so we may continue to tow with it when we take our bicycles. We're also unsure which vehicle to use when we plan longer adventures, especially out west where the charging infrastructure seems less developed at this time.
