Anxiously awaiting the delivery of a TAG XL Boondock later this fall and trying to buy a few things here and there while I await doing the pickup. Trying to find ways to maximize storage and the walls seem like best place to add some storage options. But not sure what the best technique is to attach, I've seen some advise against hammering I assume to prevent leaks from the outside. But what works best for you all? Is any part of the trailer magnetic? Do suction cups work in the heat? I've seen people reference velcro as the best bet for attaching art to the wall would that work for some basic storage containers as well? I'm also trying to come up with some ways to customize the interior to make it feel more homey without doing any damage to the vehicle... I'd like to have some form of window coverings, what do you recommend for attaching curtains? Are there any peel and stick wallpapers that work well when the camper is storage that won't peel off in the GA heat? Would decals work better? Really just want this to be like the cool fort I never had as a kid...lol Any advice is GREATLY APPRECIATED!!
