Good comment about testing fully loaded. I just picked up a 20 kw
electric furnace heating assembly. I'll derate it by running the
elements on 120 rather than 240, makes for a nice switch selectable 5 kw
load bank. The OP could make do with 2 or 3 stove burner elements.

 



Check the _actual_ draw on the heater assembly at 120 V (with proper air
or water running through it).  It may turn out to be anywhere from 2 kW
to 10 kW.

I did a quick check when I got the unit: Each element is rated 2500
watts at 240v. That would be 625 watts at 120. I measured the cold
resistance on a couple of them at 23.1 ohms and 23.8 ohms, ran one of
them on 120 line voltage, measured 122 volts, 5 amps, 612 watts on a
real wattmeter. I was surprised it was that close to the rated specs.
The good part was that it runs cool enough that a fan is not mandatory.

Tongue weight is a bit light if you plan to actually tow it on the
highway. Rule of thumb for smaller trailers is tongue weight = 10% of
gross trailer weight, more if the CG is high. The short tongue and light
tongue weight will really wag badly. Move the unit about 2" forward and
you should be good to go.

  I'll keep that rule of thumb in mind. I got lucky on the balance, I
centered
the welder with the engine to the rear and it came out as stated. The welder
is 45-3/8" and the trailer is 48", no more room to move unit forward.
If it had been negative weight on the tongue, I had thoughts about moving
the axle/spring mounting location. Or rotating the welder 180*, I might
still look into that as it would be slightly more convenient to have the
controls and connections in the rear.
