Howdy Ray! I love ours, we have the same 450P-RV. I like it because of the Duty Cycle: (100% @ 100 PSI) The 400P-RV was only ( 33% @ 100 PSI) Duty Cycle.
I use it also to power my brad & staple nailer gun. To make up for not having a tank I just hook up more hoses for the air volume. This is the reason I went with the 450P-RV with the 100% duty cycle. It works real good for a tankless pump.
The only bad thing is the alligator clamps for battery connection are kinda week & junky. I just replaced with better ones. Also made quick disconnects to hook up to our main battery bank in the 5er or pick-up.
We set-up Kim & Jessie’s old 5th wheel the same way.
Hope this helps you out…………………………….
Hi Ray, I have had the 400P-RV model for about two years now. I like it a lot. No problems with it. I think it would be easier to have a short air chuck for when you don’t need to reach back thru the dual tires. I don’t use the pressure gauge that came with it to often. I use a heavy duty gauge I used to use when I was trucking.
Dude! My viaire needs a new home. I think one of the abandoned battery holders should do
Good thing you made that pigtail or I wouldn’t have anywhere to get power to it.
FYI… I got the smaller one which heats up quicker so not good for extended run time.
