Hi Maineh,
This issues has come up before and not just on the older campers.
Here is a pic of Medbill's Toyota and his newer Sunline. I think it was a 2007 T195SR. I think he had super springs and has the issue of hanging down far enough.
His post shows up here on the 2nd page. He has the Reese round bar where yours is the EAZ lift that Camco bought I believe.

I can give you some similar ground clearances to help you compare.
This one was mine. I only had 6". I never hit the DC but did bounce the shank twice in my own drive way...errr. This was a 18 1/2" ball height on my 2500 Suburban.
Here is a 2004 T2499, 18 1/2" ball height with the Reese round bar on a Jeep Commander.
This is a 2005 T2363 on a 1/2 ton Chevy truck. This was a low one. The ball height was not much, maybe in the same 15" range. I know of 2 SOC members who tow just like this as I helped them with their hitch. I'll have to see if I can find the ball height in the 2363. The older on line floor plans use to list it
They where on the edge of what was the clearance limit on the DC. It was about 5" maybe 4 1/2" in a slight ground hump. However the DC can flex up if pushing up occurs and things keep going.
In your round bar case the bottom of the WD bars under the hitch head may be the first area to hit when the truck rear tires dips down into a hole. The round bars do not flex up like the DC, they just hit and lift the back of the truck.
5" may be your limit and you will need to watch you do not bounce the truck. If you looking for options, the Equal-I-izer 600# or now 400# WD hitch by Progress Mfg may be one. They do not hang down like the round bar hitch does.
Equal-i-zer® Hitch - The “American Original” with 4-Point Sway Control™ and Weight Distribution
If you find some one with a T1950 or up to at least a T2363 they may be in this same 15" ball height area. Odds are high one of them has a round bar hitch and can maybe go measure the ground clearance they have to compare.
Hope this helps.
