I do not have a slide out, and my generator is just behind the drivers seat, in the first compartment behind the front left tire. I have a 1997 Bounder 30E.
I have seen several motorhomes with slide outs and the generator is under the drivers side slide out. The exhaust normally only goes out to the edge of the motorhome, and is fixed, so when the slide is out, then the exhaust gas can stick around under the slide out. With possible air leaks, I would not want the exhaust under the slide out.
I also do not want the generator under my bed! I can understand your concerns, especially if your plan might include running the generator all night long in the hot desert!
I have also seen RV's with the generator in the back, behind the rear axle on the drivers side. In that case, the exhaust went out the back (it was about 8' long) so that it stays away from the RV. This can be important in some camping situations, like the Balloon Fiesta, where they park the RV's only 8' apart from each other.
Good luck!
Fred.
Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
