If you use a hitch like the
Hensley Arrowor similar, big winds and push from passing trucks will be non issue.
It makes a travel trailer tow just as well or better than a 5th wheel.
For me, as much as I hate to admit it, spending as much time in a rig as you plan on doing would require a rig with a lot of room and plenty of storage. The only way you will get that in abundance is with a 5th wheel trailer. We live in ours for 3 months straight every winter and also many times during the summer but sure could use more storage space! We also do not have room for a washer/dryer which many of our friends have in their rigs. If I were going to replace our present 30ft TT I think it would probably be with a 5th wheel.
There are many considerations to think about when deciding what to get, but you can rest assured that being blown around by the wind, uneven pavement, or passing trucks should not be one of them.
Hope this helps.:)
