RVers with Class B vans or Class A motorhomes don't usually have a problem when choosing a VIAIR, but RVers in Class Cs, towables and fifth wheels sometimes have issues deciding between the VIAIR 300P-RVS and the 400P-RVS.  It is about a $190 jump in price from the 300 model to the 400 model, but the 400 model has more of the features that many RVers are looking for in an RV tire inflator plus an additional 30-foot hose often needed for longer RVs.  Let's look at these 2 models in more detail for those who need help deciding:

The VIAIR 400P-RVS and 450P-RVS come with additional hoses and extra hose accessories that the other models do not have.  Oftentimes, even those with smaller RVs choose the 400 and 450 models just to get the additional accessories.  One of them is the gas-station style air gun with a 40-inch 90-degree twist on chuck which makes airing up tires more convenient - and puts less strain on your knees, for sure!
