Saw a picture on here earlier today; Person had a 252XD attached to the back of a Ford Explorer. Clearly anything CAN be done. Should it be done is REALLY REALLY subjective.
@Babin Farms is completely correct. There is no "one" solution or answer here. Some questions to ask.
- How far are you towing typically?
- A minivan will do the job if you're going 1 mile each way once a year. Of you're going 3 hours each way twice a weekend, then you're gonna want something heavier.
- What are you towing?
- An SX190 can be towed with most anything this side of a bicycle, a 252XD is going to want something heavier duty.
- What kind of of vehicle and brand do you want/like?
- Our Traverse wasn't worth a crap towing our AR190 with a full load of people. My Trailblazer SS was GREAT. Similar size, but COMPLETELY different powertrain and chassis setup between the two.
- REALLY REALLY hoping my Q7 is closer to the SS and further from the Traverse. Haven't test yet though
- Can you get away with a full-size SUV or do you want something smaller? Full-size SUV's (Yukon/Expedition/Armada/Sequoia/etc.) typically have really good tow ratings and always have good reviews.
- What kind of risk are you willing to accept in terms of safety and equipment longevity?
- The more headroom you remove, the more likely you are to have a problem. Basic "safety factor" theory.
Keep in mind that you have to watch both towable rating, as well as Gross Combined Vehicle Weight Rating (GCVWR). This is typically in the 8-10k range for midsize SUVs. Assume a 4,500lb curb weight, and 1k in passengers and gear, and your allowable tow rating has dropped off significantly. I did an example of this with my 9,200lb tow rated GMC a few years ago for a family vacation. I was down to something like 3,800lbs of "overhead" once we were all loaded up and ready to go.
I recently downgraded my tow vehicle capacity as well (2015 GMC Sierra to 2017 Audi Q7). Tow rating dropped from 9,200lbs to 7,700lbs. I passed on a number of other "midsize" SUV's as I wanted to ensure I had greater than 6k tow rating if/when we upgrade our 190. Only a few SUV's out there in the midsize range with greater than 5k tow rating. IMO, 5k isn't enough for a 24ft Yamaha. It's borderline on the 21ft Yamahas, depending on persons/gear/boat/etc.
Happy hunting.
