I keep my RV just across the street and have been through this park for a long time, before & after KOA.  All the services you would want are here and they have a workable mesh wifi system.  Another plus is that a Verizon and ATT cell tower is <2 miles away.  The staff are pleasant and approachable.   KOA has recently modernized this park and added a lot of new sites to the south and east of the old facility. IMHO the whole place is a class act and I think you will like it

There are sufficient transient sites to accommodate I-80/90 /I-69 /US-20 traffic. However, there are a lot of seasonal RV's that are congregated towards the lake to the south:  There is a beach on this property.  The transient sites are, near the US-20 road, to the north are and easily accessible.  I do not consider this to be a extremely loud road but there is large truck traffic day/night; however, I have not noticed "jake brake" use and the road is straight and flat in front of the park.

FYI - disclosure:  I am in no way associated, employed or incented to make this review.  I am considered to be a local guide by Google but not incented by them either.  If Dyrt allows,  I will later add pictures I have taken over the years from land and air. Also, as a parting bit of info, I have kayaked extensively in this long chain of lakes that this RV park is located on and you can go on for days.
