Underbelly tape was 6 inches wide and fairly easy to handle.
The tape was really tough and sticky and did what it promised. Used it to repair falling insullation under our house. Was glad we bought two rolls because it's a great product for similar future projects.

This is definitely the tape to fix camper underbelly tears or to do work and reseal
This worked VERY well to seal some slits in the underbelly of our camper. I would definitely buy this product again and recommend it. Mice got into the camper through openings where they ran plumbing and didn't bother to properly seal. I cut some slits in that underbelly protective layer to vacuum out seeds, stained insulation, etc. Once everything was successfully cleaned up and restored, I washed it all down with alcohol and used this tape to seal the slits that I had made. The tape was super sticky, even a little hard to get off the roll, but it stuck extremely well to the camper's protective layer. Knowing what the dealer would have charged to do the same work that I did myself, this tape was an excellent value for the money. It also looked just like the protective material that came under the camper, so it didn't look at all out of place. I've been about 2000 miles with it on the camper so far, through rain, gravel and dirt roads, and it continues to stick perfectly in place. I would say that it has great durability for having survived as well as it has so far.

Good temporary fix
This underbelly tape is significantly different than the professional tape, but it is a good temporary tape if it's needed in a pinch. It cuts well, isn't thin and adheres well enough to get to service appointments.

Decent quality
It seems to be doing its job. Definitely very sticky and not easy to pull back off to reset. But decent quality. Feels like it will hold up.

This tape works great
What can I say but this works perfectly! Needed to cut into the all-season underbelly of our travel trailer to fix the leaking connection of the black tank cleaning wand. Once that was repaired, this tape made quick work of fixing the cut we had to make to to the repair. Lasted through the past HOT summer, through some cold and rainy weather on a trip to Washington and strong winds flowing right through it's semi-open carport here at home over the past month or two. This tape STICKS! The price was right and we have a lot left over should we ever need it again. You just never know what will happen when driving down the road. Yes, we recommend this tape. Happy travels all!

Short term solution
The material seems to be good quality, however, the adhesive is terrible quality and started pealing off shortly after being applied.

Sticky and works
Used this for the underbelly that had tears in it. Super sticky, so don’t use scissors or shears, need a flat surface and a box cutter type tool.

This is hands down the best tape you will EVER use to seal underneath an RV slide. I have tried several others and this blows them all away. Thick, super sticky, and has the correct appearance and texture. Awesome product.

Used windex to clean surfaces to adhere to. Let dry completely. Cut tape to fit with lots of overlap. Work the tape to ensure it is well stuck including all edges. Does a nice job so far.

Tape looks like it will do the job but starts coming off within a month. I cleaned the surfaces before applying..didn’t help. Coming off and I haven’t even moved the trailer.
