What tires come on that Silverback are they 614’s?
Lots of posts on gas vs diesel. For me its mileage, climbing mountains, tank range and moving my 14k rig when it needs to be quick.
Roadside Insurance-lots of discussion on this too. One thing is certain...you need it as tows can get expensive in a hurry. We have Good Sams...heard good and bad about it, we have never had to use it. I read last week that your auto carrier may offer the same coverage (ie, State Farm in my case). I also use them to insure my trailer. It’s on my list to check into this week.
Camping clubs: Good Sams is a given if you plan to shop at camping world (discount). Also Passport is worth it if the places you go support it. I figure for the purchase price you will likely get your money back if you travel a weekend a mont or so.
Congrats on the new rig and good luck.
