good way to carry gas for portable gen ?

Since you are looking at a first trip, dry camping with a "new to you" motorhome. Why bother with it for this short trip?
From all the questions and concerns you have voiced recently, may I suggest you simplify some.
Take the trip, keep carry along gear to a minimum and use the built in systems fully. ie full water/propane tanks, empty waste tanks, and use the unit as the builder designed it for. Then after getting a basic idea of how long batteries, water, propane, etc last, and what doesn't last as long as you had hoped, then start finding ways to enhance it.
From your post, I can almost envision you working yourself to death trying to do everything possible on this first trip, and not taking the time to relax and enjoy it.

Good luck.

No truck this is a motorhome, I added the info to my profile but not sure if its showing up ??

Go back into your profile, then go to preferences, then add your RV details in your signature. I'd suggest adding that it's a Class A. There are so many makes and models out there, it can be very confusing.

Most of the Honda's have a fuel pump...(many other brands are gravity fed).

There are simply systems you can get cheaply online that connect to the Honda fuel cap with a hose running to the extra tank. Because it has a fuel pump, it will suck fuel from the auxiliary tank (doesn't work with gravity fed).

Simple and neat.

Not sure where you can store a fuel jug in your MH but make sure it's away from the living areas and anywhere with electrical that isn't spark protected.

That's a good point. But, some only read the OP and respond without reading the other posts. So they don't know the whole story.

If the OP had a signature line it would show up with his original post just like signature line shows below this post.

I'm not so sure that you even need a generator if you rig has an on board genny. Do you plann on doing extensive boon docking? Or are you just thinking in case of the on board generator failing? Are you worried that the on board genny will use too much fuel?

Just to answer your question, well to tell you what I do really, I have a 2 gallon saftey can that I carry in the basement compartment with the genny with a full tank of fues.

Is it safe? As safe as any suggestion you have received so far.

If I carry a small Honda gen do I carry a gas can or someone was saying cut the Onan gen fuel line and put in a T and a hose ??

IF you are familiar with small gas engines and can locate the fuel pump and there is a reasonable enough hose after the fuel pump to splice in the tee, go for it. The outlet of the tee must have a good brass shutoff.

Parts required :
• Brass or fuel compatible tee
• Brass shutoff
• 6 hose clamps
• Fuel hose (you can you clear vinyl hose, AFTER the shutoff

I am not a fan of worm gear clamps on small hoses. Too easy to over tighten. I bought and assortment of spring clamps and use those.

All small gasoline engine are different, but older lawnmower style engines typically use 1/4" ID hose, but not what you buy at an auto parts store. Auto fuel hose is usually 1/2" OD. Small engine fuel hose is usually 7/16". Many small engines now use metric size fuel

I made a wooden box that fits the gas can with a piece of rubber on the bottom. I have that in the pick up bed. I have seen some people with a welded bracket on the tongue where they keep a 5 gallon can.

This is a motorhome
