Our Adco served us well for 7 seasons on our ROO 23SS with 2 very tiny scuff marks that DH used the trusty duct tape on. We got ours at the CW annual fall sale and they usually include tire covers at n/c. I just told the rep the year, make and model of our camper and they sent the appropriate one. Yes, it should fit over the propane tanks and IIRC ours also fit over the tongue, but not positive. Remember, it has to go over the A/C unit and any vent covers you have, so that requires more size. Now that we've moved to the darkside, guess we'd better get a move on ordering a new cover....hadn't realized time had flown quite so fast.
