I know you mention queen size but I find the full size measurement seems to be more accurate. See chart attached. http://www.costco.com/NovaForm®-3%22-Pure-Comfort-Memory-Foam-Mattress-Topper.product.11765557.htmlRe: ADCO Class C Windshield CoverHere is a food site for that: http://www.sunpromfg.net/Class-C-Windshield-Covers-s/47.htmRe: APP. for RV ParksEven though the Ultimate Campground app. is for iPhone and iPad it can still be accessed by computer. http://www.ultimatecampgrounds.com/uc/index.php This app for android coming soon I hearRe: APP. for RV ParksTake a look at the Ultimate Campground app https://itunes.apple.com/us/app/ultimate-us-public-campground/id698323700?mt=8Re: furnace exhaustOnce fixed, consider installing insect screen. http://www.youtube.com/watch?v=2lcVtEy9DWURe: Chains on rear of class COutside dual usually. Run the inner dual up on some kind of block to give you clearance on the outer dual. Check your manual for type of chain required. For instance, my 2003 Ford requires type S chain which is thinner than normal chain. Not much clearance between duals.

When it first came out I had to use a cheap inverter. After about a year later they did come out with a DC cord that plugs in to lighter socket. Works great. Expensive but worth it IMO. Using 2 trojan t-105 6 volt batts and have never had a problem even when using humidifier.Re: 12 volt helpYou are receiving some good advice. Charge then up then test. If they will not hold charge then load test them at any auto parts. Here is a good link if you want to test yourself. http://blog.rv.net/2009/11/testing-your-battery-state-of-charge/Re: Attached bicycle to RV ladderI have used one for years to carry 2 bikes. Get one that attaches to the rails and not just hang on the step. See Surco 901. Use budgie cords to keep wheels from swinging. http://tinyurl.com/nz8l2z6 Joe Hamm
