I checked and your tire is one inch higher than my Jayco was and your axle housing is probably smaller also every little bit makes a difference. Can the Sprinter chassis tow a car?

Hi Bill
I have a 2018 Thor Siesta 24SS built on a Mercedes Benz Sprinter 3500 chassis. I tow my 2014 Ford Flex 4 door with my Sprinter no problem. We use a tow dolly and put over 5,000 miles on it this past summer.

You'll be surprised of the good outcome and massive torque.

My sad 1/2", two generation old 18v ryobi takes mine off.

(also consider a torque multiplier just in case some ham fisted newb gets on those lugs)

I now have a torque multiplier. On my fifth wheel I purchased new tires. They did use a torque wrench, but I discovered that it was only after over torquing the nuts. Their response was that their air guns are calibrated! After I returned from a 9k mile cross country trip, I decided to check the bearings and replace the shocks that were worthless. I had to use a four foot pipe on a breaker bar to get one nut off. All others had large thread shavings when the nuts came off. All new lugs and lug nuts. I am thankful that they over torqued so that the nuts could not back off when I went across country. I never drive without loosing the nuts and torquing them myself now when a wheel has to be removed. Cars as well.

In that case I would back the lug nuts off with a 1/2" or 3/4" breaker bar and then see what the impact wrench will do.

I can get the lug nuts off fairly easily with a 1/2" breaker bar on my Axis with 16" wheels and a torque spec of 140 ft lbs. I bet your Porter Cable impact wrench can too if they aren't too tight.

My observation is that most car service centers only check with a torque wrench after fully gunning the lugs nuts on. What is the probability that some are over torqued?

When I looked at the tires it showed a 5,000 pound hitch and it was capable of only 4,220 pounds. Even your Ford flex empty is 4,471 to 4,839 lbs depending on the model

With a big torque wrench.

I had to get a new one too

I have one and a torque multiplier. Not that I want to do the work, but if I have no choice. I used this several times in the past. Now with the torque multiplier, I should not have to handle this beast.

I got the Milwaukee 2767 1/2” drive impact that has 1400 ft lbs nut busting torque. What a beast! It breaks the lug nuts loose (177 ft lbs factory spec torque) without any problem. Best tool I’ve bought yet. I took a quick 8 second video but it won’t let me upload it.
