If you live in a southern region then go with the Adco Polypropylene Storage Lot RV Cover for Travel Trailer part # 290-74843. view full answer...

The Westlake ST225/75R15 # LH36FR will definitely be a good replacement for your current tire and wheel set up. The 6 on 5 1/2 bolt pattern is the industry standard for 6 lug wheels on trailers, so that will not be a problem at all. With aluminum wheels, you do need to go with a longer lug nut due to the holes being recessed into the aluminum, so the Lionshead # LHLR103 will be the ones I suggest. These also do not include a center cap, so you will need to go with the Lionshead # LHCS108-SI60C... view full answer...
