We have a 2011 3055RL and contemplated having an Onan installed in the front bay. The cost stopped us, so we continue to use our Honda EU2000 and it works very well for us, but we don't and can't run the AC with it, nor need to where we camp at high altitude. In our travels we came upon a couple with an Onan in their front bay (different brand fifth, but doesn't matter) and they have to carry additional LP tanks for it because it uses a lot. The Honda is very economical and can run on a tank in econo mode for several days. For this reason, we prefer to use our portable Honda.
