I've been towing an Airstream for about 6 months and it's been a ton of fun...other than the fact it gets dinged every 1500 miles or so by some tiny rock. I have Cooper LTZs on the LR4 which are awesome but love picking up the stray pebble or 4. Anyone have a good recommendation on a way to tame this? I check treads now anytime I set out, but it's not a bulletproof solution obviously. Thanks!
