We've done that a LOT (at least 6 years) with two KPA500s on Honday 
2000i generators for CQP and 7QP expeditions. Two can run on a single 
Honda, but with some voltage sag between the gen and the unregulated PSU 
in the KPA500. You have to set the "right" tap in the KPA500's primary 
(low, med, high) that hits the "just right" HV so that the KPA doesn't 
protect because it's too high key up and too low key down. With two KPAs 
on a single 2000i, both can be running CW at the same time at about 
300W. Maybe both full power if one CW, one SSB.

W6GJB's contesting trailer is set up for two K3/P3/SVGA/KPA500/KAT500 
stations, which we mostly run on CW. Several years ago, he bought the 
paralleling kit, so we run two in parallel, both in economode, running 
our entire station.

A single 2000i will run an entire single-TX station in economode.

Glen (GJB) has done propane conversions for his 2000i, and recently for 
my new 2200i. There's a company that sells the kit. Much safer and more 
convenient than gasoline.
