60 means nothing....you can only have so many 28 this or 28 that.
For example, we had a 3010, 3120 and a 3100....so what do you call another 30' model? Well that became the 3050.
We should do like other companies and have the letters then mean something. So 31BH would be a 31 Bunk House. 31SS is a Super slide. 31FW is a 31' full wall slide. But once you're down a certain path its hard to turn back.
