Struggling with Asset Purchasing LBO

I’m currently interning at a lower middle market PE firm and was asked to build an asset purchase LBO for a heavy equipment dealer.

I had a couple of questions:

1. The CIM provides a 3-year segment breakdown (new equipment, used equipment, parts & services, F&I), but limited detail on volumes or unit economics. Given how cyclical this business is, how do people typically build a defensible forecast for segment-level revenue growth? My initial approach was to anchor on historical trends and adjust for macro, but I’m struggling to justify forward assumptions given volatility.

2. More broadly, how would you structure an asset purchase LBO differently from a standard equity purchase model (particularly around balance sheet setup and sources/uses)?

Any advice or frameworks would be greatly appreciated. template? My firm didn't provide a lot of guidance on how to structure it honestly.
