x2 on the Viair compressors. I have the 400P. Very quiet and can pump up to 150 psi according to Viair. Note that Viair recommends you connect the compressor to your TV's battery and have the engine running since they draw a fair bit of power so a permanent mount in your 5er may not be ideal. I bought a 50' hybrid 3/8" air hose for mine because the single coiled hose it came with just isn't long enough. If I were to order it again, I'd upgrade to the "RV" package that comes with an extension coiled hose and pockets for both hoses.
