Sangheili,

1. Don't think you'll find a Still dealer in the US - mainly in Europe & other off shore countries. But no one company makes a substantially superior lift truck than the other.
2. With most freezer & brine application the first thing you need to do is have the equipment ordered from the manufacturer with the proper freezer & corrosion protection. Freezer protection is relatively inexpensive compared to corrosion protection. In my opinion, the Japanese companies are very good at it as in their country they consume a lot of fish & other seafoods.
3. Then the most important issue is a good & regular (based on actual per day usage) planned maintenance program (for lift trucks, battery/charger) performed by specific equipment knowledgeable, trained & experienced personnel vs shade trees - start here by talking to the lift truck dealers you are considering.
4. #3 is the key in determining which product you select & which one is the best "bang" for your buck. Remember the adage "you can pay me now or pay me later" as you go through this process of evaluation.
