Do I need replacement spring bars?

[GilnJo]

Good morning all,
I presently tow a 2011 Shamrock 23SS (GVWR 6300# +/-) with a an old workhorse 97 Chevy Suburban 1/2 ton (280K miles). I'm replacing the Suburban soon with a 2007 3/4 ton GMC Yukon XL. I have a Reece 1000/10000 WDH now, my question is: are the existing spring bars sufficient, and are there any other adjustments needed for the hitch assembly on the new truck? Thanks all for your assistance.

The listed tongue weight of that trailer is 458 lbs. Depending on the actual tongue weight of the camper loaded for camping, 800 lb. bars may be a better fit. The 1000 lb. bars should work, but may be a little stiff.

Switching between vehicles should not affect the spring bars. But you may need to adjust the ball height to get the trailer to ride level, as well as tilting the ball mount to get the optimal weight distributing.

i have a 23SS and your actual tongue weight will be 600lbs. or more.
here's Chuck S's 23SS tongue weight on a Sherline scale:

and
stick with what you have.
i have the 1000/10000lbs. Equalizer and it's perfect.
