picking out right air compressor

I believe a 150 will do the job you are looking for. I was using a small hotdog style and it took a bit as it was limited. Add a pound or two, cycle compressor, repeat. I recently got a new compressor for home: http://www.homedepot.com/p/Husky-33-gal-Quiet-Portable-Electric-Air-Compressor-C331H/203995169#customer_reviews
Very happy! Yes I have the onboard for when I am on the road, but I like the convenience of this unit for the RV at home and for so much more!
