I enjoy that is all purpose right now and fairly bullet proof that i can loan it out and not worry it will be damaaged. One day I may put a lid on it for a rtt or mod it more in a expo direction and want to leave that option open. I really like the durability of professional spay in liners like linex but worry down the road Ill want to change something and want to drill new holes and weld up the old ones or add a rack or some thing and have no touch up option. diy roll on could be touched up but doesnt have the strength to hold up to hauling gravel for example. Is there a product that you feel is the right compromise for this?
