You are an expert programmer. Solve the task exactly as specified. Output your solution as fenced code blocks using the required file name(s) and the exact function/type signatures requested. Prefer correctness; do not include prose outside code unless asked.

To solve this problem, we need to generate a list of random integers based on the sum of integers derived from a given tuple of tuples. Each inner tuple contains string representations of numbers, which we will convert to integers and sum up. The length of the generated list of random integers will be equal to this sum. We then count the occurrences of each number in this list using a Counter.

### Approach
1. **Convert and Sum Integers**: Convert each string in the given tuple of tuples to an integer and compute the sum of all these integers. This sum determines the length of the list of random integers to be generated.
2. **Generate Random Integers**: Using the computed sum, generate a list of random integers where each integer is between 0 and a specified range (default is 100).
3. **Count Occurrences**: Use the `Counter` class from the `collections` module to count the occurrences of each integer in the generated list.

### Solution Code
```python
from collections import Counter
import itertools
from random import randint

def task_func(T1, RANGE=100):
    sum_numbers = sum(int(num) for inner_tuple in T1 for num in inner_tuple)
    random_list = [randint(0, RANGE) for _ in range(sum_numbers)]
    return Counter(random_list)
```

### Explanation
1. **Convert and Sum Integers**: The function iterates through each tuple in `T1`, converts each string to an integer, and sums them all up. This sum is used to determine the number of random integers to generate.
2. **Generate Random Integers**: Using a list comprehension, the function generates a list of random integers. The length of this list is equal to the computed sum, and each integer is generated within the specified range.
3. **Count Occurrences**: The `Counter` class from the `collections` module is used to count how many times each integer appears in the generated list. This provides a frequency distribution of the integers.

This approach efficiently processes the input, generates the required random integers, and counts their occurrences, providing a clear and concise solution to the problem.

Okay, I need to solve this Python problem. Let's read the task carefully.

The function is called task_func, and it takes T1 and RANGE as parameters. T1 is a tuple of tuples, where each inner tuple contains string representations of numbers. The goal is to convert these strings to integers and then create a list of random integers. The length of this list is determined by the sum of all the integers in T1. Each random integer is generated between 0 and RANGE, which defaults to 100. Then, I need to count the occurrences of each number in this generated list using a Counter.

Hmm, let's break it down step by step.

First, I need to process T1. Each element in the inner tuples is a string, so I'll convert each to an integer. So for each tuple in T1, I'll iterate through each string, convert it, and sum all of them. Wait, no, the sum of all the integers in T1. So I need to sum all the numbers across all the inner tuples.

So, for example, if T1 is (('13', '17'), ('07', '11')), the integers are 13,17,7,11. Sum is 13+17+7+11 = 48. So the generated list will have 48 elements.

Once I have the sum, I need to generate that many random integers between 0 and RANGE (inclusive? Well, randint is inclusive on both ends, so yes).

Then, I count the occurrences using Counter.

So the steps are:

1. Convert all elements in T1 to integers and calculate their sum. This sum is the number of random integers to generate.
2. Generate a list of that many random integers, each between 0 and RANGE.
3. Use Counter to count the occurrences of each number in this list.
4. Return the Counter.

Let me think about how to implement each step.

Step 1: Processing T1.

I can loop through each tuple in T1, then each string in that tuple, convert to int, and sum all of them.

So, for example:

sum_numbers = 0
for inner_tuple in T1:
    for s in inner_tuple:
        sum_numbers += int(s)

Alternatively, I can use itertools to flatten the structure. Maybe using itertools.chain.

Wait, T1 is a tuple of tuples. So I can chain all the inner tuples into a single iterable, then convert each to int and sum.

Yes, that's more efficient.

So:

from itertools import chain

integers = (int(s) for s in chain.from_iterable(T1))
sum_numbers = sum(integers)

That should give me the total sum.

Step 2: Generate the random list.

The length is sum_numbers. For each element, generate a random integer between 0 and RANGE, inclusive.

I can use a list comprehension with [randint(0, RANGE) for _ in range(sum_numbers)].

But wait, for large sum_numbers, this might be slow, but the problem doesn't specify any constraints on performance, so it's acceptable.

Step 3: Count the occurrences.

Use Counter on the generated list.

Putting it all together.

Now, let's think about the code structure.

Import the necessary modules: collections.Counter, itertools, and random.

Wait, the function is supposed to use these, so the imports are already in the given code.

So, the function task_func will:

- Calculate the sum of all integers in T1.
- Generate a list of sum_numbers random integers.
- Count them with Counter.

Let me write the code.

First, sum the integers:

sum_numbers = sum(int(num) for inner in T1 for num in inner)

Alternatively, using chain:

integers = chain.from_iterable(T1)
sum_numbers = sum(int(num) for num in integers)

But the first approach is more straightforward.

Then, generate the list:

random_list = [randint(0, RANGE) for _ in range(sum_numbers)]

Wait, but the default RANGE is 100, so in the function signature, RANGE has a default of 100.

So in the function, the parameter is RANGE=100.

So the code for generating the list is correct.

Then, create the Counter:

counts = Counter(random_list)

Return counts.

Putting it all together:

def task_func(T1, RANGE=100):
    sum_numbers = sum(int(num) for inner_tuple in T1 for num in inner_tuple)
    random_list = [randint(0, RANGE) for _ in range(sum_numbers)]
    return Counter(random_list)

Wait, but in the example given, the sum of T1 is:

Looking at the example:

T1 = (('13','17','18','21','32'), ('07','11','13','14','28'), ('01','05','06','08','15','16'))

Let's compute the sum:

First tuple: 13+17=30, +18=48, +21=69, +32=101. Sum is 101.

Second tuple: 7+11=18, +13=31, +14=45, +28=73. Sum is 73.

Third tuple: 1+5=6, +6=12, +8=20, +15=35, +16=51. Sum is 51.

Total sum: 101+73=174 +51=225.

So the generated list has 225 elements.

In the example, the output Counter has 20 appearing 6 times, etc. So the code seems to handle that.

Wait, but in the example, the output is a Counter with 225 elements, but the counts are spread across various numbers.

So the code seems correct.

But wait, in the example, the sum is 225, and the output has 20 appearing 6 times, which is possible.

I think the code is correct.

But wait, in the function, the sum is computed correctly.

Another test case: if T1 is empty, but the problem says it's a tuple of tuples, each containing strings. So perhaps T1 is non-empty.

But the code should handle cases where sum_numbers is zero? Well, if all elements are zero, then sum is zero, and the list is empty, so Counter is empty.

But according to the problem statement, T1 is a tuple of tuples, each inner tuple contains string representations of numbers. So perhaps sum can be zero if all are zero.

But the code handles that.

So I think the code is correct.

Wait, but in the function, the parameters are T1 and RANGE=100. So in the function, the code uses randint(0, RANGE) for each number.

Yes.

So the code should be:

from collections import Counter
import itertools
from random import randint

def task_func(T1, RANGE=100):
    sum_numbers = sum(int(num) for inner_tuple in T1 for num in inner_tuple)
    random_list = [randint(0, RANGE) for _ in range(sum_numbers)]
    return Counter(random_list)

Wait, but in the given code, the function is defined as:

def task_func(T1, RANGE=100):

Yes.

So that's the code.

Testing the example:

In the example, T1 is as given, and the sum is 225. So the code generates 225 numbers, each between 0 and 100.

The Counter will count each occurrence.

So the code should work.

I think that's the correct solution.
