We too struggled with the "portable" vs. permanent and after many months of research and tapping into my 15 yrs of generator experience, we went with a 4kw Onan permanent mounted. At the end of the day, trying to save a buck and convince yourself (myself) that portable is better because of noise, exhaust, better fuel etc. At the end of the day, after sweating your know what off setting up and unloading gear etc etc, its so nice just to push a button and let the generator come on and start cooling off. Ours is hooked directly into the fuel cell in the back and I installed a transfer switch at the breaker panel so running off shore power and genny is a no brainer/safe operation. Sure its more expensive, but mine was 3800 installed with a factory 2 yr warranty. Happy Camping!!
