HOXWELL NBTS582-4 RV trailer jack blocks are a stackable plastic support set intended for RV jacks and stabilizers. The listing describes a 4-piece, 8-inch-high set with a carry bag, though the explicit component list names only a trailer jack block, so confirm the selected listing’s package contents before buying.

## At a glance

- Stackable blocks are presented as a way to build height on uneven ground and nest for storage.
- The listing describes a built-in weep hole for drainage and a handle and rope for carrying.
- Manufacturer copy claims a 40,000-pound gross vehicle weight capacity. This is a listing claim, not an independently verified rating.

## Pros

- Stacking and nesting offer adjustable support height while helping reduce storage bulk.
- The described drainage hole may help water and debris leave the block interior.
- The listing says the blocks suit most tongue jacks, posts, feet and stabilizers.

## Before you buy

- The listing gives inconsistent dimensions: the technical details say 12 x 12 x 7.87 inches, while feature text says 12 x 12 x 8 inches and the title calls the blocks 8 inches high. Weight also differs between the listed 7.53 kg and feature copy’s 2.87 lb. The 4-piece title and carry-bag claim are not confirmed by the explicit contents list, which names only a trailer jack block. The 40,000-pound figure is described as vehicle GVW capacity, so do not treat it as a per-block load rating without clarification.

## In the box

- Trailer jack block (Included): The explicit contents list names this item. The title separately claims four pieces and a bag, which are not confirmed by that list.

## A good fit for

- RV owners seeking stackable jack or stabilizer supports for parking setups.
- Buyers who want blocks that can nest for storage and have a stated carry handle and rope.

## Less suited to

- Buyers who need a clearly confirmed per-block load rating or a verified package count before purchase.
- Buyers looking for wheel chocks or a complete RV leveling system, which are not established as included.

## Customer feedback

There is no customer review-summary text or aspect-specific feedback supplied. Aggregate ratings skew strongly toward five-star ratings, but include some low-star ratings as well. Those figures do not explain what customers liked or disliked, so they cannot confirm fit, durability, the load claim or the package contents.

## Frequently asked questions

### How many blocks are included?
The title describes four pieces, but the explicit included-components field names only a trailer jack block. Confirm the selected listing’s package count and bag inclusion before ordering.
### What load can each block support?
The listing claims that the entire vehicle can have a gross vehicle weight up to 40,000 pounds. It does not establish a per-block load rating, so do not assume the figure applies to each block.
### What are the listed dimensions?
The details give 12 x 12 x 7.87 inches, while feature text says 12 x 12 x 8 inches. Check the exact dimensions if height or fit is critical.
### Can these be stacked?
Yes. The listing describes stacking multiple blocks for height and nesting them for storage. Use them only in a setup appropriate for your RV and jack.
