Safe to tow ? Mercedes GLS with a 4500 lb travel trailer

If you want to tow that much trailer AND carry 6 people in luxury, the Navigator is by far the best option IMO. The interior is at least as good as the MLS finally, but will manage a heavy trailer far better.



Full size vans are great, but the Express and NV are riding on ancient chassis at the point. Only the Transit has any semblance of a modern driving experience, but a relatively low GCWR. I don't think any of them would meet the OP's tastes, if they were considering a GLS.
