While I have an onboard 6kw diesel generator and don't have a need for an external one, years back when we first got into RVing, and bought a nicely used '13 Blackwood fifth-wheel bunkhouse, I was 'afraid' that we would somehow 'need' full 30amp service, and bought those new and expensive Honda eU2000 and Companion generators...
I never used them, and later sold them at a good discount.
While that's one 'story' about being new to RVing and the 'generator thang', I do like the idea I saw the other day: retrofit your gas generator to run on propane.
I saw a video of another RVr doing this for their off-grid camping, and it makes good sense. For the Honda models, it looks relatively easy, and can connect to a simple 15/20lb propane tank. Since most any trailer or camper has the propane tanks already, it certainly makes sense to use that instead of carrying fuel containers, especially if your tow vehicle is a diesel.
It's a interesting retro, and similar to our 'propane to electric' conversion/retro fit for our 'propane only' water heater on my son's camper. His has the 'standing pilot/manual light' variety, but he is always 'plugged in' to electricity, so retrofitting the water heater with the 'Hot Rodd' electric element was fairly easy, and no more 'propane' needed, or a 'standing pilot light' that has to be constantly 'on', although, technically, you could still use even both at the same time, if needed.
