Hitch Clearance

We are picking up our new 2020 MS 36RKSB in a couple of weeks. I've seen some chatter about clearance issues with the newer trucks. LCI has complained that the 2020 model trucks have changed their bed depths? I saw a video about this with an F450 and a Full House; however, I believe it was more a plug for GEN-Y than a real issue.

Anyone run into issues with a new truck and clearances?

Thank you

When we bought our 5th wheel 6 months ago and I was worried about this. We have a 2020 DRV 41 RKSB4. It has 2" risers installed on the 5th wheel. Our truck is a 2020 F450 and we use a B&W Companion Hitch (Ford puck system). So far we have not had a problem. The rear of the pinbox does come very close to the top of the bed rail on very tight turns. When I say tight turns I mean outside of normal driving. I can get my truck to almost 90 deg before it gets to close for comfort.

I saw the video you were talking about and he had a bed cover on his bed that added to the problem.

I too have a bed cover - we'll see how that goes. Since your F450 is a 2020 then I'm assuming your hitch height is 19" same as mine? I'm not sure what the rail height is on the F450. Mine is a little over 21".

2" Risers? Do you mean you have a lift kit on the axles?

When my 5th wheel was built a metal tube was added between the suspension and frame to give it a 2" increase in height. If I remember right my bed inside height was 20 and 1/2 inches and 63 inches from left to right. The hitch height is approx 18 to 19 inches. When hookedup to the trailer I have 6 1/2" of clearance from the bedrail to the 5th wheel.

I talked to as many people as I could about this before buying ours and never got a 100% answer. There are just to many variables between trailers and trucks. Unfortunately you really won't know until you hookup to your 5th wheel if you have a clearance problem.

The 2020 F-450 is slightly lowered in the rear so not as a good comparison as prior years. But it is still close even without any type of bed cover rails.

My rig has 2” risers. Wish it had 3”. I have my 6” of clearance but tight turns on uneven terrain it has rubbed the side rail. No clue why truck manufacturers did that, other than to cause indigestion for owners.

Unfortunately, the pickups are not made for the average RV'er, made for the work crowd that want/need the bed capacity.

My new truck is a bit lower, but the uneven terrain thing is still an issue.

3" would be better. I ordered ours before the 2" riser was standard, $200 option at the time. And DRV would not allow the order to be 3".

If you don't know it, you can lower the IS shear springs 1", pushing the trailer up 1".

The bolt holes are already in the mounting plate.

Reality is if you raised the RV 1" at the wheels the gap at the bed will only increase around 1/8". Raise hitch or lower pinbox.

Cummins, "will only increase around 1/8"' try to tell the average RV'er what you said, or that 1000# of bike in the garage only takes about 100# off the pin....I have tried both until I'm blue in the face.
