Looked up the specs on the CC38efk you’re looking at. 41ft 8in, so actually closer to 42ft...see my comments above.
More importantly, it says dry pin weight of 2700lbs, dry weight of 14.4k and gross of 18klbs. Pretty much guarantee you will be over your rear axle weight if you get an SRW.
My VL 320GK has a “dry pin” of 2600, dry weight of 12something, and gross of 16k. Actually loaded it weighs in around 15.5k (extra batteries, stuff, and water). Actual pin weight is 3550. I’m right on the spec’d capacity of my SRW.
For any “mid-high end” 5er like a CC you really need a 1T to stay within weights; and a dually if you’re over ~35ft. Lots travel over their rear axle weights, I won’t recommend it but that’s your call. I’ve seen MANY that started out with an SRW and then weighed their rigs ready for travel and subsequently lost a bunch of money trading in their new SRW for a dually. Make sure you make an informed decision.
