There are pros and cons to each design. If you sit out the winter instead of moving a lot the 5th wheel might be the better choice for space. If your snow birding now discuss with your neighbors what they like and dislike about their units. Since your husband has a cdl the 5er will be a more comfortable match to his experience.
For us the 5er was the better choice as we tend to stay put. Only you can determine what rig best meets your needs. Pickups or tow vehicles for the larger 5er's are not cheap. Since your husband has a cdl a converted semi might make a more cost efficient tow vehicle depending upon the size 5er you'd chose.
There's an option for everyone. Just have to find the one that fits. Good luck.
