How is your present generator installed--stationary or on a slide platform? Is your present generator being replaced because of hours, too small, or some other reason? Is your present generator diesel?
Will the new generator fit in the same compartment?
Is rebuilding your present generator an option?
Obvisiouly, i don't understand your installation or the need to replace the generator.
DRIVE A 2001 NEWMAR DUTCH STAR WITH 330 HP CUMMINS AND TOW A RANGER 4X4. TRAVEL WITH SPOUSE AND PET TINKER BELL OUR CORGIE.
I'm not aware of your needs or situation but I would consider the following:
How many years and how many hours do I plan to run the generator?
Is one quieter than the other? Where will I use the genny's {campground or boon dockinig) and will a noise difference affect me?
Is there a fuel operating difference between the two i'm considering?
What is the life of each generator i'm considering?
Is overhauling my existing genny an option? Am I capable of doing the work (replacement or overhaul) myself or do I need to pay someone?
Is there a good trade school available that would overhaul for the cost of parts? Sometime they are looking for work to use for teaching.
Is a good low hour used genny an option? Colaw and Visione are two possible sources of used genny's. I've bought from both. Colaw is in Carthage, Mo and Visione is in southern Ky just off I 65 near Corbin.
Both can arrange for having the work done.
Are all connections between the old and new exactly alike? Things like remote start, fuel lines, power out to the coach and 12 v to the gennys starter?
