Replacing Batteries on my 2022 Tab 400

DanaTAB400

I can't find any Harris Batteries (Original Equipment) in Salt Lake City where I am.
Amazon sells: Sun Cycle 6 volt AGM Battery (brand Go Power)
Dimensions are exactly the same as Harris Batteries: 10.24"Lx7.09"Wx9.96"H
They weight 67.25 lbs each
Would these be good replacment batteries for my trailer?

Those appear to be perfectly fine battery replacements for your dual 6V setup. They appear to be mentioned in this thread, also.

There are different 225 amp hour AGMs that have been mentioned in various threads, also. Vmax Tanks are listed in this thread.

You will also note in the first thread: there are many 400 owners who have changed those almost 140 pounds of AGM batteries for a single 230 amp hour lithium battery.   Many such batteries will simply drop in:  the LiTime 230 amp hour batteries are well reviewed, etc. 

A 230 amp hour lithium will increase your usable battery amp hours from about 120 to more than 200.  And, be less expensive.

Adding to what @pthomas745 wrote, there are more 200Ah LiFePo batteries that are in the $400 range which are smaller and lighter than two 6V batteries. LiFePo batteries also can be discharged lower (they protect themselves against over-discharge) so slightly less nominal capacity does not affect real-world camping use.
