I still went with a Short Bed on my new ordered truck because of the following;

The Long Bed payload is about 250 lbs less than short bed
Turning Radius is 5 feet more with a long bed
I would be over gross on payload with a long bed towing my 337RLS

I went with the Andersen hitch initially because of the 200#s of weight savings over a conventional 5th wheel hitch. I love the hitch. I can take it out in less than 5 minutes and lift it out with one hand. It hangs on the garage wall when not in the truck bed.

This combination gives me more than enough turning angle. I never want to go over 45-50 degrees due to the stress on the trailer suspension. I can easily see the cap/cab clearance in the back window and/or rear view mirrors.

Here’s another view of max turn.

That’s a relatively tight turn. From the angle it doesn’t look like the truck is squatting at all.

It’s deceiving. I measured the truck squat. It squats 3” once the Reflection is hitched.

So I’ve found a 2018 F350 very similar to yours. It has a CC of 3417. What is your opinion, any problems, safety issues...? The Anderson Ultimate is 35 pounds, the wife and I are 380 and if I use your 2800#, still puts me less than 3417. This particular vehicle doesn’t have the 5th wheel hitch prep, so an additional computation will be required.

Thanks,
Tony

FGAWR = 5990#, RGAWR = 7230# Did not look at tire ratings. According to the window sticker it has the LT275/65R20’s unknown brand at this point.
