wolfee,
There's a ton of info on the forum about adding fans, instructions, various brands, and etc.
Try a forum search, using each of the brand names in the search box... lots to read.
We've had both brands that you mentioned [each with & without the remote], in various RV's over the years.
I, personally, prefer the Maxx-Fan since I'm a light sleeper
Most recent purchase was Maxx-Fan 5100K,
an all-in-one low profile unit [no need to add roof vent cover & only 5" high when closed].
Suggestion - regardless of brand, choose one with "reversible" air flow.
