Going to the store can get you killed......What IFs just aren't in my 'worry book'.
Which RV.....that's a personal choice.
We looked at MHs and 5vrs for our FT rig.
We chose a 5vr for our needs/wants. MHs would have worked also.
Each have pros/cons.......for us 5vr had more in the pro column.
For others its the opposite.
First you have to figure out what it is you want in a FT rig
Make a list of what you want/need then go fill it.........you're the ones paying for it/using it-------get what works for you.
