For those of you on a shoe string budget here are a few suggestions for you
Here is a super cheap out fit.
For power you can get a Champion 4000 watt gas generator from Shucks for only $300
For heat get your self a 240 volt 4,000 watt electric heater $165
For summer you get your self a Window Air conditioner for $50
(slide it out your sleepr door)
Total parts $515 / Labor $300? = $815
How ever keeping generator filled with gas is a major pain
I think the next step up would me a good in between the good $7,000 - $10,000 APU's and the $515 version
4500 watt diesel generator with enclosed case and wireless remote start $2139

Then if you want heating and cooling I would add a dometic HVAC system ($1200 installed ?)
That is what many APU's use. http://www.dometictruck.com/aahselfcont.php
If all you want is heat go with the 240 volt 4000 watt heater for $165
Estimated total parts and labor: $3,339 or $2739 w/o A/C
Either way can't beat the price.
