We don't full time and may not need that much storage. At my age the last thing I need to do is acquire more "stuff"!

Thanks for all the input! Invaluable.
Some take the weight off the axle, some will turn and follow the rig and others actually lift the axle. My '09 Country Coach lifts the tires off the ground when I remember to push the button. In reverse it does automatically lift however. But I have the HWH Active Air which added the auto lift in reverse.

Ride and handling as others have mentioned are the two biggest factors in the advantage of a tag axle. One other one that has not been mentioned is the shorter rear overhang. We have a dip at the end of our road which resulted in our former 40 foot coach dragging the mud flap. It dragged enough to actually bend the mud flap. Now with the shorter overhang we donít drag going onto the main road.

One additional comment of clarification. The OP will lose a storage bin due to the tag....he's looking at a 40' coach. If you get a 45' coach with tag, you do not loose that storage bin.

When you make tight turns or back up you want to lift the tag or minimize pressure on it. Ours has a switch to raise it. And it has a 14 mph limit when it goes down automatically when you go over that speed. I like to lift ours manually so I just do it when I see a really tight turn. Our 42' coach has an amazingly tight turning radius because it is a tag rig. Then you lift the rear tag it shortens the chassis turning length and the turning circle becomes tighter.

There were a lot more short tag rigs "in the olden days" than there are now.

Used to be a hard 20,000 pound rear axle weight limit, per the government, now it's up to 24,000.
Generally, 40' rigs are happy with this.

Over 40', all new coaches are tags.
Ours has a 17k front end, 20k drive, and 12k tag.

Regulations determine if a tag is needed. --Maximum single rear axle weight is 20,000 pounds, tandem axle weight can go to 34000 pounds.

"SGhost".....you heard all the reasons, but there is one more that has an impact on a 40' coach. Because the 42' and above coaches are pretty much required to have a tag, they turning radius really isn't different between coaches of the same length.

Having a tag on a 40' is rare, where most 40' coaches only run a single axle. With the addition of the tag, you push the drive axle three feet farther forward, giving it a really tight turning radius. Currently the only company still making a 40' coach with a tag is Newmar.

I didn't want anything longer than 40' for several reasons, like licensing, towing and campground access, but I wanted a coach with a tag. My Newmar with the tag and Comfort Steer is rock solid, especially in the wind.

If you are saying that 20,000 rear axle is max by regulations that is incorrect. Our coach has a 24,000 rear and 13,500 front axle. Also, we have a GVWR 37,500 with a 7221 CC.

Not anymore, they extended the commercial bus exemption to motorhomes some years ago so now the legal limit is 24,000 on the drive axle, but the tandem weight stayed the same.
My rig has a 20,000# front axle rating, a 20,000# drive and 14,000# tag. However, going by the part number on the drive it's actually a 25,000# rating which is good because I'm actually at 23,000 on it.

In campgrounds/parking lots that have speed bumps, you will feel the softness with a tag. Just as you drive over the hump with the drive axle, the tag tires soften the downward motion as you drive over.

Our tag does not lift off of the ground, it just releases most of the pressure. I did see the tag come off of the ground once. I was at the Prevost service center and as the tech was driving the coach into the service bay, there was a slight incline at the entrance into the stall. As the drive axle rolled over the slight 'rise' of the concrete, the tag came off of the ground. So, it must carry very little weight when lifted.

Our axle ratings are:

Front- 19,000
Drive- 22,500
Tag- 14,000
----------------
Total- 55,500 lbs.

Safe travels,
Mark

Great information! I'm think my mind is made up to go for a tag no matter. The final call will be the wife's preference for a full bath and 1/2. I'm trying hard to stay at the 40 mark, may stretch to the 42" but I'm not going to a 45'. Thats too big for some campgrounds and may limit me in storage facilities as well.

Great feedback, Thanks to all.

SGhost, our first coach was a 2008 Monaco Dynasty, 42 ft., which was a good size as we had a tag axle, king bed, washer and dryer. The bathroom was a walk-through with a sink and shower on one side and a private toilet on the other.

When we got our second coach (in signature), I wondered if the extra 3 feet would make a difference. And yes, I can tell the difference when going around corners, etc., but no big issues.

We drove the Dynasty (bought new) to just shy of 70k and now have 56K on the current coach. We have fit where ever we have wanted to go without any problems. We don't go to public campgrounds which can/could be limiting.

Go with the floor plan that works for you, everything else will fall into place.

Good luck,
Mark

The above is correct for commercial vehicles but not for MHs since 2012 when 24K single axle were made legal on RVs... like buses.

OP, get a 42’ rig with a tag... you will not regret it.
