I'm fortunate in that my LP bottles are in a side storage compartment a couple feet back from the front. My rack is adjustable forward and back to allow for different configurations. I bought the 18" taller rack that gives me extra height, I would think this rack allows enough adjustment for LP bottles, especially if your children still have smaller bikes. I have 4 bikes in the truck bed already so I only need to put the smallest bikes on the rack. The added bonus is some serious support for my battery rack where I plan to mount a pair of larger batteries.
Edit: With a little fabrication it would be easy to increase the rack height even more, if stability is an issue you have alot of steel up front there to strap/brace to. Toppoprails is way too much $$ for such a thin lookin rack IMO.
No never did purchase that one but am looking for plans so I could build my own. As it is now the bikes fit in our Jayco quite nicely. On our old TV, we had the front receiver with the bike rack stuck WAY out there, but found it very intimidating and not to mention blocking the headlights, turn signals etc. No problem with air flow to the rad, just the others I mentioned. Toppoprails is a little pricey.
Hope this helps.
